Childhood and family (1879—1895)

Leon Trotsky was born Lev Davidovich Bronstein (Russian: ??? ????????? ?????????) on 7 November 1879, in Yanovka, Kherson Province of the Russian Empire (today's Bobrynets Raion, Kirovohrad Oblast, Ukraine), a small village from the nearest post office. He was the fifth, and favorite child of a well-to-do farmer, David Leontyevich Bronstein (1847—1922) and Anna Bronstein (1850—1910). The family was Jewish, although it was not religious. The languages spoken in his home were Russian and Ukrainian instead of Yiddish. Trotsky's younger sister, Olga, married Lev Kamenev, a leading Bolshevik.

According to a notable pushkinist Alexander Latsis and his pupil Vladimir Kozarovetsky, Lev Trotsky might be a great-grandson of the greatest Russian poet Alexander Pushkin. Latsis studies suggested that Pushkin had an illegitimate son Leonty from Polish woman Angelica Dembinsky. The baby is alluded in many of Pushkin's poetry. In turn Leonty Dembinsky had an affair with his cousin. Their child was given for adoption to a Jewish family of Bronsteins and got the name David Lentyevich Bronstein, who was Leon's father. The hypothesis was criticised by pushkinist Lazar Freydgeim who labelled it "fantasies on an empty place"

When Trotsky was nine, his father sent him to Odessa to be educated and he was enrolled in a historically German school, which became Russified during his years in Odessa, consequent to the Imperial government's policy of Russification. As Isaac Deutscher points out in his biography of Trotsky, Odessa was then a bustling cosmopolitan port city, very unlike the typical Russian city of the time. This environment contributed to the development of the young man's international outlook.

Although it is stated in his autobiography My Life that he was never perfectly fluent in any language but Russian and Ukrainian, Raymond Molinier wrote that Trotsky spoke fluent French.

Revolutionary activity and exile (1896—1902)

Trotsky became involved in revolutionary activities in 1896 after moving to Nikolayev (now Mykolaiv). At first a narodnik (revolutionary populist), he was introduced to Marxism later that year and was originally opposed to it. But during periods of exile and imprisonment he gradually became a Marxist. Instead of pursuing a mathematics degree, Trotsky helped organize the South Russian Workers' Union in Nikolayev in early 1897. Using the name 'Lvov', he wrote and printed leaflets and proclamations, distributed revolutionary pamphlets and popularized socialist ideas among industrial workers and revolutionary students.

In January 1898, over 200 members of the union, including Trotsky, were arrested, and he spent the next two years in prison awaiting trial. Two months after his imprisonment, the first Congress of the newly formed Russian Social Democratic Labor Party (RSDLP) was held, and from then on Trotsky considered himself a member of the party. While in prison, he married fellow Marxist Aleksandra Sokolovskaya. While serving his sentence he studied philosophy. In 1900 he was sentenced to four years in exile in Ust-Kut and Verkholensk (see map) in the Irkutsk region of Siberia, where his first two daughters, Nina Nevelson and Zinaida Volkova, were born.

In Siberia, Trotsky became aware of the differences within the party, which had been decimated by arrests in 1898 and 1899. Some social democrats known as "economists" argued that the party should focus on helping industrial workers improve their lot in life. Others argued that overthrowing the monarchy was more important and that a well organized and disciplined revolutionary party was essential. The latter were led by the London-based newspaper Iskra, or in English, Spark, which was founded in 1900. Trotsky quickly sided with the Iskra position.

First emigration and second marriage (1902—1903)

Trotsky escaped from Siberia in the summer of 1902. It is said he adopted the name of a jailer of the Odessa prison in which he had earlier been held, and this became his primary revolutionary pseudonym. Once abroad, he moved to London to join Georgy Plekhanov, Vladimir Lenin, Julius Martov and other editors of Iskra. Under the pen name Pero ("feather" or "pen" in Russian), Trotsky soon became one of the paper's leading authors.

Unknown to Trotsky, the six editors of Iskra were evenly split between the "old guard" led by Plekhanov and the "new guard" led by Lenin and Martov. Not only were Plekhanov's supporters older (in their 40s and 50s), but they had also spent the previous 20 years in European exile together. Members of the new guard were in their early 30s and had only recently come from Russia. Lenin, who was trying to establish a permanent majority against Plekhanov within Iskra, expected Trotsky, then 23, to side with the new guard and wrote in March 1903:

Because of Plekhanov's opposition, Trotsky did not become a full member of the board, but from then on participated in its meetings in an advisory capacity, which earned him Plekhanov's enmity.

In late 1902, Trotsky met Natalia Sedova, who soon became his companion and, from 1903 until his death, his wife. They had two children together, Lev Sedov (b. 1906) and Sergei Sedov (b. 1908). As Trotsky later explained, after the 1917 revolution:

But the name change remained a technicality and he never used the name "Sedov" either privately or publicly. Natalia Sedova sometimes signed her name "Sedova-Trotskaya". Trotsky and his first wife, Aleksandra Sokolovskaya, maintained a friendly relationship until she disappeared in 1935 during the Great Purges.

Split with Lenin (1903—1904)

In the meantime, after a period of secret police repression and internal confusion that followed the first party Congress in 1898, Iskra succeeded in convening the party's 2nd congress in London in August 1903, Trotsky and other Iskra editors attended. The first congress went as planned, with Iskra supporters handily defeating the few "economist" delegates. Then the congress discussed the position of the Jewish Bund, which had co-founded the RSDLP in 1898 but wanted to remain autonomous within the party.

Shortly thereafter, pro-Iskra delegates unexpectedly split into two factions. Lenin and his supporters (known as Bolsheviks) argued for a smaller but highly organized party. Martov and his supporters (known as Mensheviks) argued for a larger and less disciplined party. In a surprise development, Trotsky and most of the Iskra editors supported Martov and the Mensheviks while Plekhanov supported Lenin and the Bolsheviks.

During 1903 and 1904, many members changed sides in the factions. Plekhanov soon parted ways with the Bolsheviks. Trotsky left the Mensheviks in September 1904 over their insistence on an alliance with Russian liberals and their opposition to a reconciliation with Lenin and the Bolsheviks. From then until 1917 he described himself as a "non-factional social democrat".

Trotsky spent much of his time between 1904 and 1917 trying to reconcile different groups within the party, which resulted in many clashes with Lenin and other prominent party members. Trotsky later conceded he had been wrong in opposing Lenin on the issue of the party. During these years Trotsky began developing his theory of permanent revolution, which led to a close working relationship with Alexander Parvus in 1904—1907.

1905 revolution and trial (1905—1906)

After the events of Bloody Sunday, Trotsky secretly returned to Russia in February 1905. At first he wrote leaflets for an underground printing press in Kiev, but soon moved to the capital, Saint Petersburg, where he worked with both Bolsheviks, such as Central Committee member Leonid Krasin, and the local Menshevik committee, which he pushed in a more radical direction. The latter, however, were betrayed by a secret police agent in May, and Trotsky had to flee to rural Finland. There he worked on fleshing out his theory of permanent revolution until October, when a nationwide strike made it possible for him to return to St. Petersburg.

After returning to the capital, Trotsky and Parvus took over the newspaper Russian Gazette and increased its circulation to 500,000. Trotsky also co-founded Nachalo ("The Beginning") with Parvus and the Mensheviks, which proved to be very successful.

Just before Trotsky's return, the Mensheviks had independently come up with the same idea that Trotsky had...an elected non-party revolutionary organization representing the capital's workers, the first Soviet ("Council") of Workers. By the time of Trotsky's arrival, the St. Petersburg Soviet was already functioning headed by Khrustalyov-Nosar (Georgy Nosar, alias Pyotr Khrustalyov), a compromise figure, and proved to be very popular with the workers in spite of the Bolsheviks' original opposition. Trotsky joined the Soviet under the name "Yanovsky" (after the village he was born in, Yanovka) and was elected vice-Chairman. He did much of the actual work at the Soviet and, after Khrustalev-Nosar's arrest on 26 November, was elected its chairman. On 2 December, the Soviet issued a proclamation which included the following statement about the Tsarist government and its foreign debts:

The following day, the Soviet was surrounded by troops loyal to the government and the deputies were arrested.

Trotsky and other Soviet leaders were tried in 1906 on charges of supporting an armed rebellion. At the trial, Trotsky delivered some of the best speeches of his life and solidified his reputation as an effective public speaker, which he confirmed in 1917—1920. He was convicted and sentenced to deportation.

Second emigration (1907—1914)

En route to exile in Obdorsk, Siberia in January 1907, Trotsky escaped at Berezov and once again made his way to London, where he attended the 5th Congress of the RSDLP. In October, he moved to Vienna where he often took part in the activities of the Austrian Social Democratic Party and, occasionally, of the German Social Democratic Party, for seven years.

In Vienna, Trotsky became close to Adolph Joffe, his friend for the next 20 years, who introduced him to psychoanalysis. In October 1908 he started a bi-weekly Russian language social democratic paper aimed at Russian workers called Pravda ("Truth"), which he co-edited with Joffe, Matvey Skobelev and Victor Kopp and which was smuggled into Russia. The paper avoided factional politics and proved popular with Russian industrial workers. Both the Bolsheviks and the Mensheviks split multiple times after the failure of the 1905—1907 revolution. When various Bolshevik and Menshevik factions tried to re-unite at the January 1910 RSDLP Central Committee meeting in Paris over Lenin's objections, Trotsky's Pravda was made a party-financed 'central organ'. Lev Kamenev, Trotsky's brother-in-law, was added to the editorial board from the Bolsheviks, but the unification attempts failed in August 1910 when Kamenev resigned from the board amid mutual recriminations. Trotsky continued publishing Pravda for another two years until it finally folded in April 1912.

The Bolsheviks started a new workers-oriented newspaper in St. Petersburg on 22 April 1912, and also called it Pravda. Trotsky was so upset by what he saw as a usurpation of his newspaper's name that in April 1913 he wrote a letter to Nikolay Chkheidze, a Menshevik leader, bitterly denouncing Lenin and the Bolsheviks. Though he quickly got over the disagreement, the letter was intercepted by the police, and a copy was put into their archives. Shortly after Lenin's death in 1924, the letter was pulled out of the archives and made public by his opponents within the Communist Party, and was used to paint him as Lenin's enemy.

This was a period of heightened tension within the RSDLP and led to numerous frictions between Trotsky, the Bolsheviks and the Mensheviks. The most serious disagreement that Trotsky and the Mensheviks had with Lenin at the time was over the issue of "expropriations", i.e., armed robberies of banks and other companies by Bolshevik groups to procure money for the Party, which had been banned by the 5th Congress, but continued by the Bolsheviks.

In January 1912, the majority of the Bolshevik faction led by Lenin and a few Mensheviks held a conference in Prague and expelled their opponents from the party. In response, Trotsky organized a "unification" conference of social democratic factions in Vienna in August 1912 (a.k.a. "The August Bloc") and tried to re-unite the party. The attempt was generally unsuccessful.

In Vienna, Trotsky continuously published articles in radical Russian and Ukrainian newspapers like Kievskaya Mysl under a variety of pseudonyms, often "Antid Oto". In September 1912, Kievskaya Mysl sent him to the Balkans as its war correspondent, where he covered the two Balkan Wars for the next year and became a close friend of Christian Rakovsky, later a leading Soviet politician and Trotsky's ally in the Soviet Communist Party.

On 3 August 1914, at the outbreak of World War I which pitted Austria-Hungary against the Russian empire, Trotsky was forced to flee Vienna for neutral Switzerland to avoid arrest as a Russian émigré.

World War I (1914—1917)

The outbreak of World War I caused a sudden realignment within the RSDLP and other European social democratic parties over the issues of war, revolution, pacifism and internationalism. Within the RSDLP, Lenin, Trotsky and Martov advocated various internationalist anti-war positions, while Plekhanov and other social democrats (both Bolsheviks and Mensheviks) supported the Russian government to some extent.

In Switzerland, Trotsky briefly worked within the Swiss Socialist Party, prompting it to adopt an internationalist resolution, and wrote a book against the war, The War and the International. The thrust of the book was against the pro-war position taken by the European social democratic parties, primarily the German party.Trotsky moved to France on 19 November 1914, as a war correspondent for the Kievskaya Mysl. In January 1915 he began editing (at first with Martov, who soon resigned as the paper moved to the left) Nashe Slovo ("Our Word"), an internationalist socialist newspaper, in Paris. He adopted the slogan of "peace without indemnities or annexations, peace without conquerors or conquered", which didn't go quite as far as Lenin, who advocated Russia's defeat in the war and demanded a complete break with the Second International.

Trotsky attended the Zimmerwald Conference of anti-war socialists in September 1915 and advocated a middle course between those who, like Martov, would stay within the Second International at any cost and those who, like Lenin, would break with the Second International and form a Third International. The conference adopted the middle line proposed by Trotsky. At first opposed to it, in the end Lenin voted for Trotsky's resolution to avoid a split among anti-war socialists.

On 31 March Trotsky was deported from France to Spain for his anti-war activities. Spanish authorities did not let him stay and he was deported to the United States on 25 December 1916. He arrived in New York City on 13 January 1917 where he stayed for nearly three months at 1522 Vyse Avenue in the Bronx (New York City). In New York, he wrote articles for the local Russian language socialist newspaper Novy Mir and the Yiddish language daily Der Forverts in translation and made speeches to Russian émigrés. He was officially earning some $15 a week.

Trotsky was living in New York City when the February Revolution of 1917 overthrew Tsar Nicholas II. He left New York on 27 March but his ship, the SS Kristianiafjord, was intercepted by British naval officials in Canada at Halifax, Nova Scotia and he spent a month detained at Amherst, Nova Scotia. After initial hesitation, the Russian foreign minister Pavel Milyukov was forced to demand that Trotsky be released, and the British government freed Trotsky on 29 April. He finally made his way back to Russia on 4 May.

Upon his return, Trotsky was in substantive agreement with the Bolshevik position, but did not join them right away. Russian social democrats were split into at least six groups and the Bolsheviks were waiting for the next party Congress to determine which factions to merge with. Trotsky temporarily joined the Mezhraiontsy, a regional social democratic organization in St. Petersburg, and became one of its leaders. At the First Congress of Soviets in June, he was elected a member of the first All-Russian Central Executive Committee ("VTsIK") from the Mezhraiontsy faction.

After an unsuccessful pro-Bolshevik uprising in Petrograd, Trotsky was arrested on 7 August 1917, but was released 40 days later in the aftermath of the failed counter-revolutionary uprising by Lavr Kornilov. After the Bolsheviks gained a majority in the Petrograd Soviet, Trotsky was elected Chairman on 8 October. He sided with Lenin against Grigory Zinoviev and Lev Kamenev when the Bolshevik Central Committee discussed staging an armed uprising and he led the efforts to overthrow the Provisional Government headed by Aleksandr Kerensky.

The following summary of Trotsky's role in 1917 was written by Stalin in Pravda, 10 November 1918. (Although this passage was quoted in Stalin's book "The October Revolution" issued in 1934, it was expunged in Stalin's Works released in 1949.)

After the success of the uprising on 7—8 November, Trotsky led the efforts to repel a counter-attack by Cossacks under General Pyotr Krasnov and other troops still loyal to the overthrown Provisional Government at Gatchina. Allied with Lenin, he successfully defeated attempts by other Bolshevik Central Committee members (Zinoviev, Kamenev, Alexei Rykov, etc.) to share power with other socialist parties.

By the end of 1917, Trotsky was unquestionably the second man in the Bolshevik Party after Lenin, overshadowing the ambitious Zinoviev, who had been Lenin's top lieutenant over the previous decade, but whose star appeared to be fading. This turnaround led to enmity between the two Bolshevik leaders which lasted until 1926 and did much to destroy them both.

Commissar for Foreign Affairs and Brest-Litovsk (1917—1918)

After the Bolsheviks came to power, Trotsky became the People's Commissar for Foreign Affairs and published the secret treaties previously signed by the Triple Entente that detailed plans for post-war reallocation of colonies and redrawing state borders.

Trotsky led the Soviet delegation during the peace negotiations in Brest-Litovsk from 22 December 1917 to 10 February 1918. At that time the Soviet government was split on the issue. Left Communists, led by Nikolai Bukharin, continued to believe that there could be no peace between a Soviet republic and a capitalist country and that only a revolutionary war leading to a pan-European Soviet republic would bring a durable peace. They cited the successes of the newly formed (15 January 1918) voluntary Red Army against Polish forces of Gen. Józef Dowbor-Mu?nicki in Belarus, White forces in the Don region, and newly independent Ukrainian forces as proof that the Red Army could repel German forces, especially if propaganda and asymmetrical warfare were used. They did not mind holding talks with the Germans as a means of exposing German imperial ambitions (territorial gains, reparation, etc.) in the hope of accelerating the hoped?for Soviet revolution in the West, but they were dead set against signing any peace treaty. In case of a German ultimatum, they advocated proclaiming a revolutionary war against Germany in order to inspire Russian and European workers to fight for socialism. This opinion was shared by Left Socialist Revolutionaries, who were then the Bolsheviks' junior partners in a coalition government.

Lenin, who had earlier hoped for a speedy Soviet revolution in Germany and other parts of Europe, quickly decided that the imperial government of Germany was still firmly in control and that, without a strong Russian military, an armed conflict with Germany would lead to a collapse of the Soviet government in Russia. He agreed with the Left Communists that ultimately a pan-European Soviet revolution would solve all problems, but until then the Bolsheviks had to stay in power. Lenin did not mind prolonging the negotiating process for maximum propaganda effect, but, from January 1918 on, advocated signing a separate peace treaty if faced with a German ultimatum.

Trotsky's position was between these two Bolshevik factions. Like Lenin, he admitted that the old Russian military, inherited from the monarchy and the Provisional Government and in advanced stages of decomposition, was unable to fight:

But he agreed with the Left Communists that a separate peace treaty with an imperialist power would be a terrible morale and material blow to the Soviet government, negate all its military and political successes of 1917 and 1918, resurrect the notion that the Bolsheviks secretly allied with the German government, and cause an upsurge of internal resistance. He argued that any German ultimatum should be refused, and that this may well lead to an uprising in Germany, or at least inspire German soldiers to disobey their officers since any German offensive would be a naked grab for territories. He wrote in 1925:

Throughout January and February 1918, Lenin's position was supported by 7 members of the Bolshevik Central Committee and Bukharin's by 4. Trotsky had 4 votes (his own, Felix Dzerzhinsky's, Nikolai Krestinsky's and Adolph Joffe's) and, since he held the balance of power, he was able to pursue his policy in Brest-Litovsk. When he could no longer delay the negotiations, he withdrew from the talks on 10 February 1918, refusing to sign on Germany's harsh terms. After a brief hiatus, the Central Powers notified the Soviet government that they would no longer observe the truce after 17 February. At this point Lenin again argued that the Soviet government had done all it could to explain its position to Western workers and that it was time to accept the terms. Trotsky refused to support Lenin since he was waiting to see whether German workers would rebel and whether German soldiers would refuse to follow orders.

Germany resumed military operations on 18 February. Within a day, it became clear that the German army was capable of conducting offensive operations and that Red Army detachments, which were relatively small, poorly organized and poorly led, were no match for it. In the evening of 18 February 1918, Trotsky and his supporters in the committee abstained and Lenin's proposal was accepted 7-4. The Soviet government sent a telegram to the German side accepting the final Brest-Litovsk peace terms.

Germany did not respond for three days, and continued its offensive encountering little resistance. The response arrived on 21 February but the proposed terms were so harsh that even Lenin briefly thought that the Soviet government had no choice but to fight. But in the end, the committee again voted 7-4 on 23 February 1918; the Treaty of Brest-Litovsk was signed on 3 March and ratified on 15 March 1918. Since he was so closely associated with the policy previously followed by the Soviet delegation at Brest-Litovsk, Trotsky resigned from his position as Commissar for Foreign Affairs in order to remove a potential obstacle to the new policy.

Head of the Red Army (spring 1918)

The failure of the recently formed Red Army to resist the German offensive in February 1918 revealed its weaknesses: insufficient numbers, lack of knowledgeable officers, and near absence of coordination and subordination. Celebrated and feared Baltic Fleet sailors, one of the bastions of the new regime led by Pavel Dybenko, shamefully fled from the German army at Narva. The notion that the Soviet state could have an effective voluntary or militia type military was seriously undermined.

Trotsky was one of the first Bolshevik leaders to recognize the problem and he pushed for the formation of a military council of former Russian generals that would function as an advisory body. Lenin and the Bolshevik Central Committee agreed on 4 March to create the Supreme Military Council, headed by former chief of the imperial General Staff Mikhail Bonch-Bruevich. But the entire Bolshevik leadership of the Red Army, including People's Commissar (defense minister) Nikolai Podvoisky and commander-in-chief Nikolai Krylenko, protested vigorously and eventually resigned.

They believed that the Red Army should consist only of dedicated revolutionaries, rely on propaganda and force, and have elected officers. They viewed former imperial officers and generals as potential traitors who should be kept out of the new military, much less put in charge of it. Their views continued to be popular with many Bolsheviks throughout most of the Russian Civil War and their supporters, including Podvoisky, who became one of Trotsky's deputies, were a constant thorn in Trotsky's side. The discontent with Trotsky's policies of strict discipline, conscription and reliance on carefully supervised non-Communist military experts eventually led to the Military Opposition, which was active within the Communist Party in late 1918—1919.

On 13 March 1918, Trotsky's resignation as Commissar for Foreign Affairs was officially accepted and he was appointed People's Commissar of Army and Navy Affairs - in place of Podvoisky - and chairman of the Supreme Military Council. The post of commander-in-chief was abolished, and Trotsky gained full control of the Red Army, responsible only to the Communist Party leadership, whose Left Socialist Revolutionary allies had left the government over Brest-Litovsk. With the help of his faithful deputy Ephraim Sklyansky, Trotsky spent the rest of the Civil War transforming the Red Army from a ragtag network of small and fiercely independent detachments into a large and disciplined military machine, through forced conscription, party controlled blocking squads, compulsory obedience and officers chosen by the leadership instead of the rank and file. He defended these positions throughout his life.

Civil War (1918—1920)

1918

Trotsky's managerial and organization-building skills with the Soviet military were soon tested. In May—June 1918, the Czechoslovak Legions en route from European Russia to Vladivostok rose against the Soviet government. This left the Bolsheviks with the loss of most of the country's territory, an increasingly well organized resistance by Russian anti-Communist forces (usually referred to as the White Army after their best known component) and widespread defection by the military experts that Trotsky relied on.

Trotsky and the government responded with a full-fledged mobilization, which increased the size of the Red Army from less than 300,000 in May 1918 to one million in October, and an introduction of political commissars into the army. The latter were responsible for ensuring the loyalty of military experts (who were mostly former officers in the imperial army) and co-signing their orders.

Trotsky claimed that the Red Army's organization was built on the ideas of the October Revolution. As he later wrote in his autobiography:

In dealing with deserters, Trotsky often appealed to them politically; arousing them with the ideas of the Revolution.

Given the lack of man power and the 16 invading foreign armies, Trotsky also insisted that former Tsarist officers should be used as military specialists within the Red Army, with a combination of Bolshevik political commissars to ensure the revolutionary nature of the Red Army. Lenin commented on this:

In September 1918, the government, facing continuous military difficulties, declared what amounted to martial law and reorganized the Red Army. The Supreme Military Council was abolished and the position of commander-in-chief was restored, filled by the commander of the Latvian Riflemen, Ioakim Vatsetis (a.k.a. Jukums V?cietis), who had formerly led the Eastern Front against the Czechoslovak Legions. Vatsetis was put in charge of day-to-day operations of the army while Trotsky became chairman of the newly formed Revolutionary Military Council of the Republic and retained overall control of the military. Trotsky and Vatsetis had clashed earlier in 1918 while Vatsetis and Trotsky's adviser Mikhail Bonch-Bruevich were also on unfriendly terms. Nevertheless, Trotsky eventually established a working relationship with the often prickly Vatsetis.

The reorganization caused yet another conflict between Trotsky and Stalin in late September. Trotsky appointed former imperial general Pavel Sytin to command the Southern Front, but in early October 1918 Stalin refused to accept him and so he was recalled from the front. Lenin and Yakov Sverdlov tried to make Trotsky and Stalin reconcile, but their meeting was unsuccessful.

1919

Throughout late 1918 and early 1919, there were a number of attacks on Trotsky's leadership of the Red Army, including veiled accusations in newspaper articles inspired by Stalin and a direct attack by the Military Opposition at the VIIIth Party Congress in March 1919. On the surface, he weathered them successfully and was elected one of only five full members of the first Politburo after the Congress. But he later wrote:

In mid-1919 the dissatisfied had an opportunity to mount a serious challenge to Trotsky's leadership, the Red Army grew from 800,000 to 3,000,000, and fought simultaneously on sixteen fronts.. The Red Army had defeated the White Army's spring offensive in the east and was about to cross the Ural Mountains and enter Siberia in pursuit of Admiral Alexander Kolchak's forces. But in the south, General Anton Denikin's White Russian forces advanced, and the situation deteriorated rapidly. On 6 June commander-in-chief Vatsetis ordered the Eastern Front to stop the offensive so that he could use its forces in the south. But the leadership of the Eastern Front, including its commander Sergei Kamenev (a colonel in the imperial army, not to be confused with the Politburo member Lev Kamenev), and Eastern Front Revolutionary Military Council members Ivar Smilga, Mikhail Lashevich and Sergei Gusev vigorously protested and wanted to keep emphasis on the Eastern Front. They insisted that it was vital to capture Siberia before the onset of winter and that once Kolchak's forces were broken, many more divisions would be freed up for the Southern Front. Trotsky, who had earlier had conflicts with the leadership of the Eastern Front, including a temporary removal of Kamenev in May 1919, supported Vatsetis.

At the 3—4 July Central Committee meeting, after a heated exchange the majority supported Kamenev and Smilga against Vatsetis and Trotsky. Trotsky's plan was rejected and he was much criticized for various alleged shortcomings in his leadership style, much of it of a personal nature. Stalin used this opportunity to pressure Lenin to dismiss Trotsky from his post. But when, on 5 July Trotsky offered his resignation, the Politburo and the Orgburo of the Central Committee unanimously rejected it.

Yet, a number of significant changes to the leadership of the Red Army were made. Trotsky was temporarily sent to the Southern Front, while the work in Moscow was informally coordinated by Smilga. Most members of the bloated Revolutionary Military Council who were not involved in its day to day operations, were relieved of their duties on 8 July while new members including Smilga were added. The same day, while Trotsky was already in the south, Vatsetis was suddenly arrested by the Cheka on suspicion of involvement in an anti-Soviet plot, and replaced by Sergei Kamenev.

After a few weeks in the south, Trotsky returned to Moscow and resumed control of the Red Army. A year later, Smilga and Tukhachevsky were defeated during the Battle of Warsaw, but Trotsky refused this opportunity to pay Smilga back, which earned him Smilga's friendship and later support during the intra-Party battles of the 1920s.

By October 1919 the government was in the worst crisis of the Civil War: Denikin's troops approached Tula and Moscow from the south, and General Nikolay Yudenich's troops approached Petrograd from the west. Lenin decided that since it was more important to defend Moscow, Petrograd would have to be abandoned. Trotsky argued that Petrograd needed to be defended, at least in part to prevent Estonia and Finland from intervening. In a rare reversal, Trotsky was supported by Stalin and Zinoviev and prevailed against Lenin in the Central Committee. He immediately went to Petrograd, whose leadership headed by Zinoviev he found demoralized, and organized its defense, sometimes personally stopping fleeing soldiers. By 22 October the Red Army was on the offensive and in early November Yudenich's troops were driven back to Estonia, where they were disarmed and interned. Trotsky was awarded the Order of the Red Banner for his actions in Petrograd.

1920

With the defeat of Denikin and Yudenich in late 1919, the Soviet government's emphasis shifted to economic work and Trotsky spent the winter of 1919—1920 in the Urals region trying to re-start its economy. Based on his experiences there, he proposed abandoning the policies of War Communism, which included confiscating grain from peasants, and partially restoring the grain market. But Lenin was still committed to War Communism and the proposal was rejected. Instead, Trotsky was put in charge of the country's railroads (while retaining overall control of the Red Army), which he tried to militarize in the spirit of War Communism. It wasn't until early 1921 that economic collapse and uprisings would force Lenin and the rest of the Bolshevik leadership to abandon War Communism in favor of the New Economic Policy.

Meanwhile, in early 1920 Soviet-Polish tensions eventually led to the Polish-Soviet War. In the run-up and during the war, Trotsky argued that the Red Army was exhausted and the Soviet government should sign a peace treaty with Poland as soon as possible. He also did not believe that the Red Army would find much support in Poland proper. Lenin and other Bolshevik leaders thought that the Red Army's successes in the Russian Civil War and against the Poles meant that, as Lenin said later:

But the Red Army offensive was turned back during the Battle of Warsaw in August 1920, in part because of Stalin's failure to obey Trotsky's orders in the run-up to the decisive engagements. Back in Moscow, Trotsky again argued for a peace treaty and this time prevailed.

Trade union debate (1920—1921)

In late 1920, after the Bolsheviks won the Civil War and before the Eighth and Ninth Congress of Soviets, the Communist Party had a heated and increasingly acrimonious debate over the role of trade unions in the Soviet state. The discussion split the party into many "platforms" (factions), including Lenin's, Trotsky's and Bukharin's; Bukharin eventually merged his with Trotsky's. Smaller, more radical factions like the Workers' Opposition (headed by Alexander Shlyapnikov) and the Group of Democratic Centralism were particularly active.

Trotsky's position formed while he led a special commission on the Soviet transportation system, Tsektran. He was appointed there to rebuild the rail system ruined by the Civil War. Being the Commissar of War and a revolutionary military leader, he saw a need to create a militarized "production atmosphere" by incorporating trade unions directly into the State apparatus. His unyielding stance was that in a worker's state the workers should have nothing to fear from the state, and the State should fully control the unions. In the Ninth Party Congress he argued for "such a regime under which each worker feels himself to be a soldier of labor who cannot freely dispose of himself; if he is ordered transferred, he must execute that order; if he does not do so, he will be a deserter who should be punished. Who will execute this? The trade union. It will create a new regime. That is the militarization of the working class."

Lenin sharply criticised Trotsky and accused him of "bureaucratically nagging the trade unions" and of staging "factional attacks". His view did not focus on State control as much as the concern that a new relationship was needed between the State and the rank-and-file workers. He said, "Introduction of genuine labor discipline is conceived only if the whole mass of participants in productions take a conscious part in the fulfillment of these tasks. This cannot be achieved by bureaucratic methods and orders from above." This was a debate that Lenin thought the party could not afford. His frustration with Trotsky was used by Stalin and Zinoviev with their support for Lenin's position, to improve their standing within the Bolshevik leadership at Trotsky's expense.

Disagreements threatened to get out of hand and many Bolsheviks, including Lenin, feared that the party would splinter. The Central Committee was split almost evenly between Lenin's and Trotsky's supporters, with all three Secretaries of the Central Committee (Krestinky, Yevgeny Preobrazhensky and Leonid Serebryakov) supporting Trotsky.

At a meeting of his faction at the Tenth Party Congress in March 1921, Lenin's faction won a decisive victory and a number of Trotsky's supporters (including all three secretaries of the Central Committee) lost their leadership positions. Krestinsky was replaced as a member of the Politburo by Zinoviev, who had supported Lenin. Krestinsky's place in the secretariat was taken by Vyacheslav Molotov. The congress also adopted a secret resolution on "Party unity", which banned factions within the Party except during pre-Congress discussions. The resolution was later published and used by Stalin against Trotsky and other opponents.

At the end of the Tenth Congress, after peace negotiations had failed, Trotsky gave the order for the suppression of the Kronstadt Rebellion, the last major revolt against Bolshevik rule. Years later, anarchist Emma Goldman and others criticized Trotsky's actions as Commissar for War for his role in the suppression of the rebellion, and argued that he ordered unjustified incarcerations and executions of political opponents such as anarchists, although Trotsky did not participate in the actual suppression. Some Trotskyists, most notably Abbie Bakan, have argued that the claim that the Kronstadt rebels were "counterrevolutionary" has been supported by evidence of White Army and French government support for the Kronstadt sailors' March rebellion.. Other historians, most notably Paul Avrich, claimed the evidence did not point towards this conclusion, and that the Kronstadt Rebellion was spontaneous.

Lenin's illness (1922—1923)

In late 1921 Lenin's health deteriorated, he was absent from Moscow for even longer periods, and eventually had three strokes between 26 May 1922 and 10 March 1923, which caused paralysis, loss of speech and finally death on 21 January 1924. With Lenin increasingly sidelined throughout 1922, Stalin (elevated to the newly created position of the Central Committee General Secretary earlier in the year), Zinoviev and Lev Kamenev formed a troika (triumvirate) to ensure that Trotsky, publicly the number two man in the country and Lenin's heir presumptive, would not succeed Lenin.

The rest of the recently expanded Politburo (Rykov, Mikhail Tomsky, Bukharin) was at first uncommitted, but eventually joined the troika. Stalin's power of patronagein his capacity as General Secretary clearly played a role, but Trotsky and his supporters later concluded that a more fundamental reason was the process of slow bureaucratization of the Soviet regime once the extreme conditions of the Civil War were over: much of the Bolshevik elite wanted 'normalcy' while Trotsky was personally and politically personified as representing a turbulent revolutionary period that they would much rather leave behind.

Although the exact sequence of events is unclear, evidence suggests that at first the troika nominated Trotsky to head second rate government departments (e.g., Gokhran, the State Depository for Valuables) and then, when Trotsky predictably refused, tried using it as an excuse to oust him. At this time there was speculation about Trotsky's health and whether or not he had epilepsy.

When, in mid-July 1922, Kamenev wrote a letter to the recovering Lenin to the effect that "(the Central Committee) is throwing or is ready to throw a good cannon overboard", Lenin was shocked and responded:

From then until his final stroke, Lenin spent much of his time trying to devise a way to prevent a split within the Communist Party leadership, which was reflected in Lenin's Testament. As part of this effort, on 11 September 1922 Lenin proposed that Trotsky become his deputy at the Council of People's Commissars (Sovnarkom). The Politburo approved the proposal, but Trotsky "categorically refused".

In late 1922, Lenin's relationship with Stalin deteriorated over Stalin's heavy-handed and chauvinistic handling of the issue of merging Soviet republics into one federal state, the Union of Soviet Socialist Republics (USSR). At that point, according to Trotsky's autobiography,Lenin offered Trotsky an alliance against Soviet bureaucracy in general and Stalin in particular. The alliance proved effective on the issue of foreign trade, but it was complicated by Lenin's progressing illness. In January 1923 the relationship between Lenin and Stalin completely broke down when Stalin rudely insulted Lenin's wife, Nadezhda Krupskaya. At that point Lenin amended his Testament suggesting that Stalin should be replaced as the party's General Secretary, although the thrust of his argument was somewhat weakened by the fact that he also mildly criticized other Bolshevik leaders, including Trotsky. In March 1923, days before his third stroke, Lenin prepared a frontal assault on Stalin's "Great-Russian nationalistic campaign" against the Georgia Communist Party (the so-called Georgian Affair) and asked Trotsky to deliver the blow at the XIIth Party Congress. With Lenin no longer active, Trotsky did not raise the issue at the Congress.

At the XIIth Party Congress in April 1923, just after Lenin's final stroke, the key Central Committee reports on organizational and nationalities questions were delivered by Stalin and not by Trotsky, while Zinoviev delivered the political report of the Central Committee, traditionally Lenin's prerogative. Stalin's power of appointment had allowed him to gradually replace local party secretaries with loyal functionaries and thus control most regional delegations at the congress, which enabled him to pack the Central Committee with his supporters, mostly at the expense of Zinoviev and Kamenev's backers.

At the congress, Trotsky made a speech about intra-party democracy, among other things, but avoided a direct confrontation with the troika. The delegates, most of whom were unaware of the divisions within the Politburo, gave Trotsky a standing ovation, which couldn't help but upset the troika. The troika was further infuriated by Karl Radek's article Leon Trotsky ... Organizer of Victory published in Pravda on 14 March 1923, which seemed to anoint Trotsky as Lenin's successor.

The resolutions adopted by the XIIth Congress called, in general terms, for greater democracy within the Party, but were vague and remained unimplemented. In an important test of strength in mid-1923, the troika was able to neutralize Trotsky's friend and supporter Christian Rakovsky by removing him from his post as head of the Ukrainian government (Sovnarkom) and sending him to London as Soviet ambassador. When regional Party secretaries in Ukraine protested against Rakovsky's reassignment, they too were reassigned to various posts all over the Soviet Union.

Left opposition (1923—1924)

Starting in mid-1923, the Soviet economy ran into significant difficulties, which led to numerous strikes countrywide. Two secret groups within the Communist Party, “Workers' Truth” and “Workers' Group”, were uncovered and suppressed by the Soviet secret police.

On 8 October 1923 Trotsky sent a letter to the Central Committee and the Central Control Commission, attributing these difficulties to lack of intra-Party democracy. Trotsky wrote:

Other senior communists who had similar concerns sent The Declaration of 46 to the Central Committee on 15 October in which they wrote:

Although the text of these letters remained secret at the time, they had a significant effect on the Party leadership and prompted a partial retreat by the troika and its supporters on the issue of intra-Party democracy, notably in Zinoviev's Pravda article published on 7 November. Throughout November, the troika tried to come up with a compromise to placate, or at least temporarily neutralize, Trotsky and his supporters. (Their task was made easier by the fact that Trotsky was sick in November and December.) The first draft of the resolution was rejected by Trotsky, which led to the formation of a special group consisting of Stalin, Trotsky and Kamenev, which was charged with drafting a mutually acceptable compromise. On 5 December, the Politburo and the Central Control Commission unanimously adopted the group's final draft as its resolution.

On 8 December Trotsky published an open letter, in which he expounded on the recently adopted resolution's ideas. The troika used his letter as an excuse to launch a campaign against Trotsky, accusing him of factionalism, setting "the youth against the fundamental generation of old revolutionary Bolsheviks" and other sins. Trotsky defended his position in a series of seven letters which were collected as The New Course in January 1924. The illusion of a "monolithic Bolshevik leadership" was thus shattered and a lively intra-Party discussion ensued, both in local Party organizations and in the pages of Pravda. The discussion lasted most of December and January until the XIIIth Party Conference of 16—18 January 1924. Those who opposed the Central Committee's position in the debate were thereafter referred to as members of the Left Opposition.

Since the troika controlled the Party apparatus through Stalin's Secretariat and Pravda through its editor Bukharin, it was able to direct the discussion and the process of delegate selection. Although Trotsky's position prevailed within the Red Army and Moscow universities and received about half the votes in the Moscow Party organization, it was defeated elsewhere, and the Conference was packed with pro-troika delegates. In the end, only three delegates voted for Trotsky's position and the Conference denounced "Trotskyism"as a "petty bourgeois deviation". After the Conference, a number of Trotsky's supporters, especially in the Red Army's Political Directorate, were removed from leading positions or reassigned. Nonetheless, Trotsky kept all of his posts and the troika was careful to emphasize that the debate was limited to Trotsky's "mistakes" and that removing Trotsky from the leadership was out of the question. In reality, Trotsky had already been cut off from the decision making process.

Immediately after the Conference, Trotsky left for a Caucasian resort to recover from his prolonged illness. On his way, he learned about Lenin's death on 21 January 1924. He was about to return when a follow up telegram from Stalin arrived, giving an incorrect date of the scheduled funeral, which would have made it impossible for Trotsky to return in time. Many commentators speculated after the fact that Trotsky's absence from Moscow in the days following Lenin's death contributed to his eventual loss to Stalin, although Trotsky generally discounted the significance of his absence.

After Lenin's death (1924)

There was little overt political disagreement within the Soviet leadership throughout most of 1924. On the surface, Trotsky remained the most prominent and popular Bolshevik leader, although his "mistakes" were often alluded to by troika partisans. Behind the scenes, he was completely cut off from the decision making process. Politburo meetings were pure formalities since all key decisions were made ahead of time by the troika and its supporters. Trotsky's control over the military was undermined by reassigning his deputy, Ephraim Sklyansky, and appointing Mikhail Frunze, who was being groomed to take Trotsky's place.

At the thirteenth Party Congress in May, Trotsky delivered a conciliatory speech:

The attempt at reconciliation, however, did not stop troika supporters from taking potshots at him.

In the meantime, the Left Opposition, which had coagulated somewhat unexpectedly in late 1923 and lacked a definite platform aside from general dissatisfaction with the intra-Party "regime", began to crystallize. It lost some less dedicated members to the harassment by the troika, but it also began formulating a program. Economically, the Left Opposition and its theoretician Yevgeny Preobrazhensky came out against further development of capitalist elements in the Soviet economy and in favor of faster industrialization. That put them at odds with Bukharin and Rykov, the "Right" group within the Party, who supported troika at the time. On the question of world revolution, Trotsky and Karl Radek saw a period of stability in Europe while Stalin and Zinoviev confidently predicted an "acceleration" of revolution in Western Europe in 1924. On the theoretical plane, Trotsky remained committed to the Bolshevik idea that the Soviet Union could not create a true socialist society in the absence of the world revolution, while Stalin gradually came up with a policy of building 'Socialism in One Country'. These ideological divisions provided much of the intellectual basis for the political divide between Trotsky and the Left Opposition on the one hand and Stalin and his allies on the other.

At the thirteenth Congress Kamenev and Zinoviev helped Stalin defuse Lenin's Testament, which belatedly came to the surface. But just after the congress, the troika, always an alliance of convenience, showed signs of weakness. Stalin began making poorly veiled accusations about Zinoviev and Kamenev. Yet in October 1924, Trotsky published The Lessons of October, an extensive summary of the events of the 1917 revolution. In it, he described Zinoviev's and Kamenev's opposition to the Bolshevik seizure of power in 1917, something that the two would have preferred left unmentioned. This started a new round of intra-party struggle, which became known as the Literary Discussion, with Zinoviev and Kamenev again allied with Stalin against Trotsky. Their criticism of Trotsky was concentrated in three areas:

• Trotsky's disagreements and conflicts with Lenin and the Bolsheviks prior to 1917.
• Trotsky's alleged distortion of the events of 1917 in order to emphasize his role and diminish the roles played by other Bolsheviks.
• Trotsky's harsh treatment of his subordinates and other alleged mistakes during the Russian Civil War.

Trotsky was again sick and unable to respond while his opponents mobilized all of their resources to denounce him. They succeeded in damaging his military reputation so much that he was forced to resign as People's Commissar of Army and Fleet Affairs and Chairman of the Revolutionary Military Council on 6 January 1925. Zinoviev demanded Trotsky's expulsion from the Communist Party, but Stalin refused to go along and skillfully played the role of a moderate. Trotsky kept his Politburo seat, but was effectively put on probation.

A year in the wilderness (1925)

1925 was a difficult year for Trotsky. After the bruising Literary Discussion and losing his Red Army posts, he was effectively unemployed throughout the winter and spring. In May 1925, he was given three posts: chairman of the Concessions Committee, head of the electro-technical board, and chairman of the scientific-technical board of industry. Trotsky wrote in My Life that he "was taking a rest from politics" and "naturally plunged into his new line of work up to my ears", but some contemporary accounts paint a picture of a remote and distracted man. Later in the year, Trotsky resigned his two technical positions (claiming Stalin-instigated interference and sabotage) and concentrated on his work in the Concessions Committee.

In one of the few political developments that affected Trotsky in 1925, the circumstances surrounding the controversy around Lenin's Testament were described by American Marxist Max Eastman in his book Since Lenin Died (1925). The Soviet leadership denounced Eastman's account and used party discipline to force Trotsky to write an article denying Eastman's version of the events.

In the meantime, the troika finally broke up. Bukharin and Rykov sided with Stalin while Krupskaya and Soviet Commissar of Finance Grigory Sokolnikov aligned with Zinoviev and Kamenev. The struggle became open at the September 1925 meeting of the Central Committee and came to a head at the XIVth Party Congress in December 1925. With only the Leningrad Party organization behind them, Zinoviev and Kamenev, dubbed The New Opposition, were thoroughly defeated while Trotsky refused to get involved in the fight and didn't speak at the Congress.

United Opposition (1926—1927)

During a lull in the intra-party fighting in the spring of 1926, Zinoviev, Kamenev and their supporters in the “New Opposition” gravitated closer to Trotsky's supporters and the two groups soon formed an alliance, which also incorporated some smaller opposition groups within the Communist Party. The alliance became known as the “United Opposition”.

The United Opposition was repeatedly threatened with sanctions by the Stalinist leadership of the Communist Party and Trotsky had to agree to tactical retreats, mostly to preserve his alliance with Zinoviev and Kamenev. The opposition remained united against Stalin throughout 1926 and 1927, especially on the issue of the Chinese Revolution. The methods used by the Stalinists against the Opposition became more and more extreme. At the XVth Party Conference in October 1926 Trotsky could barely speak because of interruptions and catcalls, and at the end of the Conference he lost his Politburo seat. In 1927 Stalin started using the GPU (Soviet secret police) to infiltrate and discredit the opposition. Rank and file oppositionists were increasingly harassed, sometimes expelled from the Party and even arrested.

Defeat and exile (1927—1928)

In October 1927, Trotsky and Zinoviev were expelled from the Central Committee. When the United Opposition tried to organize independent demonstrations commemorating the 10th anniversary of the Bolshevik seizure of power in November 1927, the demonstrators were dispersed by force and Trotsky and Zinoviev were expelled from the Communist Party on 12 November. Their leading supporters, from Kamenev down, were expelled in December 1927 by the XVth Party Congress, which paved the way for mass expulsions of rank and file oppositionists as well as internal exile of opposition leaders in early 1928.

When the XVth Party Congress made Opposition views incompatible with membership in the Communist Party, Zinoviev, Kamenev and their supporters capitulated and renounced their alliance with the Left Opposition. Trotsky and most of his followers, on the other hand, refused to surrender and stayed the course.Trotsky was exiled to Alma Ata in Kazakhstan on 31 January 1928. He was expelled from the Soviet Union to Turkey in February 1929, accompanied by his wife Natalia Sedova and his son Lev Sedov.

After Trotsky's expulsion from the country, exiled Trotskyists began to waver and, between 1929 and 1934, most of the leading members of the Opposition surrendered to Stalin, "admitted their mistakes" and were reinstated in the Communist Party. Christian Rakovsky, who served as an inspiration for Trotsky between 1929 and 1934 while he was in Siberian exile, was the last prominent Trotskyist to capitulate. Almost all of them perished in the Great Purges just a few years later.

Trotsky was deported from the Soviet Union in February 1929. His first station in exile was at Büyükada off the coast of Istanbul, Turkey where he stayed for the next four years. There were many former White Army officers in Istanbul, which put Trotsky's life in danger, but a number of Trotsky's European supporters volunteered to serve as bodyguards and assured his safety.

In 1933 Trotsky was offered asylum in France by Prime Minister Édouard Daladier. He stayed first at Royan, then at Barbizon. He was not allowed to visit Paris. In 1935 he was given to understand he was no longer welcome in France. After weighing alternatives, he moved to Norway. Having obtained permission from then-Justice Minister Trygve Lie to enter the country, Trotsky became a guest of Konrad Knudsen near Oslo. After two yearsallegedly under influence from the Soviet Unionhe was put under house arrest. His transfer to Mexico on a freighter was arranged after consultations with Norwegian officials. Mexican President Lázaro Cárdenas welcomed him warmly, even arranging for a special train to bring him to Mexico City from the port of Tampico.

Trotsky lived in the Coyoacán area of Mexico City at the home (The Blue House) of the painter Diego Rivera and Rivera's wife and fellow painter, Frida Kahlo (with whom he had an affair). His final move was a few blocks away to a residence on Avenida Viena in May 1939, following a break with Rivera.

He remained a prolific writer in exile, penning several key works, including his History of the Russian Revolution (1930) and The Revolution Betrayed (1936), a critique of the Soviet Union under Stalinism. Trotsky argued that the Soviet state had become a “degenerated workers' state” controlled by an undemocratic bureaucracy, which would eventually either be overthrown via a political revolution establishing workers' democracy, or degenerate into a capitalist class.

While in Mexico, Trotsky also worked closely with James P. Cannon, Joseph Hansen, and Farrell Dobbs of the Socialist Workers Party of the United States, and other supporters.

Cannon, a long-time leading member of the American communist movement, had supported Trotsky in the struggle against Stalinism since he first read Trotsky's criticisms of the Soviet Union in 1928. Trotsky's critique of the Stalinist regime, though banned, was distributed to leaders of the Comintern. Among his other supporters was Chen Duxiu, founder of the Chinese Communist Party.

Moscow show trials

In August 1936, the first Moscow show trial of the so-called "Trotskyite-Zinovievite Terrorist Center" was staged in front of an international audience. During the trial, Zinoviev, Kamenev and 14 other accused, most of them prominent Old Bolsheviks, confessed to having plotted with Trotsky to kill Stalin and other members of the Soviet leadership. The court found everybody guilty and sentenced the defendants to death, Trotsky in absentia. The second show trial of Karl Radek, Grigory Sokolnikov, Yuri Pyatakov and 14 others took place in January 1937, with even more alleged conspiracies and crimes linked to Trotsky. In April 1937, an independent "Commission of Inquiry" into the charges made against Trotsky and others at the "Moscow Trials" was held in Coyoacán, with John Dewey as chairman. The findings were published in the book Not Guilty.

Fourth International

At first Trotsky was opposed to the idea of establishing parallel Communist parties or a parallel international Communist organization that would compete with the Third International for fear of splitting the Communist movement. However, he changed his mind in mid-1933 after the Nazi takeover in Germany and the Comintern's response to it, when he proclaimed that:

In 1938, Trotsky and his supporters founded the Fourth International, which was intended to be a revolutionary and internationalist alternative to the Stalinist Comintern.

Dies Committee

Towards the end of 1939 Trotsky agreed to go to the United States to appear as a witness before the Dies Committee of the House of Representatives, a forerunner of the House Un-American Activities Committee. Representative Martin Dies, chairman of the committee, demanded the suppression of the American Communist Party. Trotsky intended to use the forum to expose the NKVD's activities against him and his followers.

He made it clear that he also intended to argue against the suppression of the American Communist Party, and to use the committee as a platform for a call to transform the world war into a world revolution. Many of his supporters argued against his appearance. When the committee learned the nature of the testimony Trotsky intended to present, it refused to hear him, and he was denied a visa to enter the United States. On hearing about it, the Stalinists immediately accused Trotsky of being in the pay of the oil magnates and the Federal Bureau of Investigation.

Final months

After quarreling with Diego Rivera, Trotsky moved to his final residence on Avenida Viena. He was ill, suffering from high blood pressure, and feared that he would suffer a cerebral hemorrhage. He even prepared himself for the possibility of ending his life through suicide.

On 27 February 1940, Trotsky wrote a document known as "Trotsky's Testament", in which he expressed his final thoughts and feelings for posterity. After forcefully denying Stalin's accusations that he had betrayed the working class, he thanked his friends, and above all his wife and dear companion, Natalia Sedova, for their loyal support:

Assassination

On 24 May 1940, Trotsky survived a raid on his home by Stalinist assassins led by GPU agent Iosif Grigulevich, Mexican painter and Stalinist David Alfaro Siqueiros, and Vittorio Vidale.In this attack a young assistant and bodyguard of Trotsky, Robert Sheldon Harte, was abducted and later murdered.

On 20 August 1940, Trotsky was attacked in his home in Mexico with an ice axe by undercover NKVD agent Ramón Mercader. The blow was poorly delivered and failed to kill Trotsky instantly, as Mercader had intended. Witnesses stated that Trotsky spat on Mercader and began struggling fiercely with him. Hearing the commotion, Trotsky's bodyguards burst into the room and nearly killed Mercader, but Trotsky stopped them, laboriously stating that the assassin should be made to answer questions. Trotsky was taken to a hospital, operated on, and survived for more than a day, dying at the age of 60 on 21 August 1940 as a result of severe brain damage. Mercader later testified at his trial:

According to James P. Cannon, the secretary of the Socialist Workers Party , Trotsky's last words were "I will not survive this attack. Stalin has finally accomplished the task he attempted unsuccessfully before."

Epilogue

Trotsky's house in Coyoacán was preserved in much the same condition as it was on the day of the assassination and is now a museum run by a board which includes his grandson Esteban Volkov. The current director of the museum is Dr. Carlos Ramirez Sandoval under whose supervision the museum has improved considerably. Trotsky's grave is located on its grounds.

Trotsky was never formally rehabilitated by the Soviet government, despite the Glasnost-era rehabilitation of most other Old Bolsheviks killed during the Great Purges. In 1987, under President Mikhail Gorbachev, Trotsky was referred to as "a hero and martyr". His son, Sergei Sedov, killed in 1937, was rehabilitated in 1988, as was Nikolai Bukharin. Above all, beginning in 1989, Trotsky's books, forbidden until 1987, were finally published in the Soviet Union.

Trotsky's grandson Vsievolod Platonovich "Esteban" Volkov (born 1926) is an active promoter of his grandfather. Trotsky's great-granddaughter, Nora Volkow (daughter of Esteban Volkov), is currently head of the U.S. National Institute on Drug Abuse.

Trotsky considered himself a "Bolshevik-Leninist", arguing for the establishment of a vanguard party. He considered himself an advocate of orthodox Marxism. His politics differed in many respects from those of Stalin or Mao Zedong, most importantly in his rejection of the theory of Socialism in One Country and his declaring the need for an international "permanent revolution". Numerous Fourth Internationalist groups around the world continue to describe themselves as Trotskyist and see themselves as standing in this tradition, although they have different interpretations of the conclusions to be drawn from this. Supporters of the Fourth International echo Trotsky's opposition to Stalinist totalitarianism, advocating political revolution, arguing that socialism cannot sustain itself without democracy.

Permanent Revolution

Permanent Revolution is the theory that the bourgeois democratic tasks in countries with delayed bourgeois democratic development can only be accomplished through the establishment of a workers' state, and that the creation of a workers' state would inevitably involve inroads against capitalist property. Thus, the accomplishment of bourgeois democratic tasks passes over into proletarian tasks.

Although most closely associated with Leon Trotsky, the call for Permanent Revolution is first found in the writings of Karl Marx and Friedrich Engels in March 1850, in the aftermath of the 1848 Revolution, in their Address of the Central Committee to the Communist League:

Trotsky's conception of Permanent Revolution is based on his understanding, drawing on the work of the founder of Russian Marxism Georgy Plekhanov, that in 'backward' countries the tasks of the Bourgeois Democratic Revolution could not be achieved by the bourgeoisie itself. This conception was first developed by Trotsky in collaboration with Alexander Parvus in late 1904—1905. The relevant articles were later collected in Trotsky's books 1905 and in Permanent Revolution, which also contains his essay "Results and Prospects".

According to Trotskyists, the October Revolution (which Trotsky directed) was the first example of a successful Permanent Revolution. The proletarian, socialist October Revolution took place precisely because the bourgeoisie, which took power in February, had not been able to solve any of the tasks of the bourgeois-democratic revolution. It had not given the land to the peasants (which the Bolsheviks did on 25 October), nor given freedom to the oppressed minority nations, nor emancipated Russia from foreign domination by ending the war which, at that point, was fought mainly to please the English and French creditors.

Trotskyists today argue that the state of the Third World shows that capitalism offers no way forward for underdeveloped countries, thus again proving the central tenet of the theory. In contrast, Stalinist policy in the former colonial countries has been characterized by the so-called Two-Stage Theory, which argues that the working class must fight for "progressive capitalism" along with the "progressive national bourgeoisie" before any attempts at socialism can be made.

The United Front

Trotsky was a central figure in the Comintern during its first four congresses. During this time he helped to generalise the strategy and tactics of the Bolsheviks to newly formed Communist parties across Europe and further afield. From 1921 onwards the united front, a method of uniting revolutionaries and reformists in common struggle while winning some of the workers to revolution, was the central strategy put forward by the Comintern.

After he was exiled and politically marginalised by Stalinism, Trotsky continued to argue for a united front against fascism in Germany and Spain. His articles on the united front represent an important part of his political legacy.
