Guicciardini was born in Florence in the year 1483, when Marsilio Ficino held him at the font of baptism. His family was illustrious and noble; and his ancestors for many generations had held the highest posts of honor in the state, as may be seen in his own genealogical Ricordi autobiografici e di famiglia (Op. med. vol. x.). After the usual education of a boy in grammar and elementary classical studies, his father, Piero, sent him to the universities of Ferrara and Padua, where he stayed until the year 1505.

The death of an uncle, who had occupied the see of Cortona with great pomp, induced the young Guicciardini to hanker after an ecclesiastical career. He already saw the scarlet robes of a cardinal awaiting him, and to this eminence he would assuredly have risen if not for his father, who declared that though he had five sons, he would not suffer one of them to enter the church in its then state of corruption and debasement. Guicciardini, whose motives were confessedly ambitious (see Ricordi, Op. med. x. 68), then turned his attention to law, and at the age of twenty-three was appointed by the Signoria of Florence to read the Institutes in public. Shortly afterwards he engaged himself in marriage to Maria, daughter of Alamanno Salviati, prompted, as he frankly tells us, by the political support which an alliance with that great family would bring him (ib. x. 71).

He was then practicing at the bar, where he won so much distinction that the Signoria, in 1512, entrusted him with an embassy to the court of the King of Aragon, Ferdinand the Catholic. "No one could remember at Florence that such a young man had ever been chosen for such an embassy," he wrote in his diary.

Thus he entered on the real work of his life as a diplomat and statesman. His conduct upon that legation was afterwards severely criticized; for his political antagonists accused him of betraying the true interests of the commonwealth, and using his influence for the restoration of the exiled house of Medici to power.

His Spanish correspondence with the Signoria (Op. med. vol. vi.) reveals the extraordinary power of observation and analysis which was a chief quality of his mind; and in Ferdinand, hypocritical and profoundly dissimulative, he found a proper object for his scientific study. To suppose that the young statesman learned his frigid statecraft in Spain would be perhaps too simple a solution of the problem offered by his character, and scarcely fair to the Italian proficients in perfidy. It is clear from Guicciardini's autobiographical memoirs that he was ambitious, calculating, avaricious and power-loving from his earliest years; and in Spain he had no more than an opportunity of studying on a large scale those political vices which already ruled the minor potentates of Italy. Still the school was pregnant with instructions for so apt a pupil.

Guicciardini issued from this first trial of his skill with an assured reputation for diplomatic ability, as that was understood in Italy. To unravel plots and weave counterplots; to meet treachery with fraud; to parry force with sleights of hand; to credit human nature with the basest motives, while the blackest crimes were contemplated with cold enthusiasm for their cleverness, was reckoned then the height of political sagacity. Guicciardini could play the game to perfection.

In 1513 Giovanni Medici, the son of Lorenzo the Magnificent, became Pope Leo X and brought Florence under Papal control. This provided opportunities for Florentines to enter Papal service, and in 1515 he began working for the papacy. Leo X made him governor of Reggio in 1516 and Modena in 1517. This was the beginning of a long career for Guicciardini in Papal administration, first under Leo X, and then his successor, Clement VII. "He governed Modena and Reggio with conspicuous success," according to The Catholic Encyclopedia, and he was appointed to govern Parma. In that city, according to the Encyclopedia, "in the confusion that followed the pope's death, he distinguished himself by his defence of Parma against the French (1521)."

In 1523 he was appointed viceregent of Romagna by Pope Clement VII ( 1478—1534). These high offices rendered Guicciardini the virtual master of the papal states beyond the Apennines, during a period of great bewilderment and difficulty. The copious correspondence relating to his administration has recently been published (Op. med. vols. vii., viii.). In 1526 Clement gave him still higher rank as lieutenant-general of the papal army. While holding this commission, he had the humiliation of witnessing from a distance the sack of Rome and the imprisonment of Clement, without being able to rouse the perfidious Duke of Urbino into activity. The blame of Clement's downfall did not rest with him; for it was merely his duty to attend the camp, and keep his master informed of the proceedings of the generals (see the Correspondence, Op. med. vols. iv., v.). Yet Guicciardini's conscience accused him, for he had previously counselled the pope to declare war, as he notes in a curious letter to himself written in 1527 (Op. med., X. 104).

Guicciardini went to Florence, but by 1527 the Medici had been expelled from the city and a republic set up. Because of his close ties to the Medici, Guicciardini was held suspect in his native city, and he fled in 1529 to the Papal Court.

Despite Guicciardini's regrets about his earlier counsel to the pope, Clement did not withdraw his confidence, and in 1531 Guicciardini was advanced to the governorship of Bologna, the most important of all the papal lord-lieutenancies (Correspondence, Op. med. vol. ix.). This post he resigned in 1534 on the election of Paul III, preferring to follow the fortunes of the Medici princes. It may here be noticed that though Guicciardini served three popes through a period of twenty years, or perhaps because of this, he hated the papacy with a deep and frozen bitterness, attributing the woes of Italy to the ambition of the church, and declaring he had seen enough of sacerdotal abominations to make him a Lutheran (see Op. med. i. 27, 104, 96, and 1st. d It., ed. Ros., ii. 218).

The same discord between his private opinions and his public actions may be traced in his conduct subsequent to 1534. As a political theorist, Guicciardini believed that the best form of government was a commonwealth administered upon the type of the Venetian constitution (Op. med. i 6; ii. 130 sq.); and we have ample evidence to prove that he had judged the tyranny of the Medici at its true worth (Op. med. i. 171, on the tyrant; the whole Storia Fiorentina and Reggimento di Firenze, lb. i. and iii., on the Medici). Yet he did not hesitate to place his powers at the disposal of the most vicious members of that house for the enslavement of Florence. In 1527 he had been declared a rebel by the Signoria on account of his well-known Medicean prejudices; and in 1530, deputed by Clement to punish the citizens after their revolt, he revenged himself with a cruelty and an avarice that were long and bitterly remembered.

, therefore, he returned to inhabit Florence in 1534, he did so as the creature of the dissolute Alessandro de Medici. Guicciardini pushed his servility so far as to defend this infamous despot at Naples in 1535, before the bar of Charles V, from the accusations brought against him by the Florentine exiles (Op. med. vol. ix). He won his case; but in the eyes of all posterity he justified the reproaches of his contemporaries, who describe him as a cruel, venal, grasping seeker after power, eager to support a despotism for the sake of honors, offices and emoluments secured for himself by a bargain with the oppressors of his country. Varchi, Nardi, Jacopo Pitti and Bernardo Segni are unanimous upon this point; but it is only the recent publication of Guicciardini's private memoirs that has made us understand the force of their invectives. To plead loyalty or honest political conviction in defence of his Medicean partisanship is now impossible, face to face with the opinions expressed in the Ricordi politici and the Storia Fiorentina. Like Machiavelli, but on a lower level, Guicciardini was willing to roll stones, or to do any dirty work for masters whom, in the depth of his soul, he detested and despised.

After the murder of Duke Alessandro in 1537, Guicciardini espoused the cause of Cosimo de Medici, a boy addicted to field sports, and unused to the game of statecraft. The wily old diplomatist hoped to rule Florence as grand vizier under this inexperienced princeling. He was mistaken, however, in his schemes, for Cosimo displayed the genius of his family for politics, and coldly dismissed his would-be lord-protector. Guicciardini retired in disgrace to his villa (at Arcetri), where he spent his last years in the composition of the Storia d'Italia. He died in 1540 without male heirs. His nephew, Lodovico Guicciardini, was also an historian particularly well-known for his 16th-century works on the Low Countries.

Guicciardini was the product of a cynical and selfish age, and his life illustrated its sordid influences. Of a cold and worldly temperament, devoid of passion, blameless in his conduct as the father of a family, faithful as the servant of his papal patrons, severe in the administration of the provinces committed to his charge, and indisputably able in his conduct of affairs, he was at the same time, and in spite of these qualities, a man whose moral nature inspires a sentiment of liveliest repugnance. It is not merely that he was ambitious, cruel, revengeful and avaricious, for these vices have existed in men far less antipathetic than Guicciardini. Over and above those faults, which made him odious to his fellow-citizens, we trace in him a meanness that our century is less willing to condone. His phlegmatic and persistent egotism, his sacrifice of truth and honor to self-interest, his acquiescence in the worst conditions of the world, if only he could use them for his own advantage, combined with the glaring discord between his opinions and his practice, form a character which would be contemptible in our eyes were it not so sinister. The social and political decrepitude of Italy, where patriotism was unknown, and only selfishness survived of all the motives that rouse men to action, found its representative and exponent in Guicciardini. When we turn from the man to the author, the decadence of the age and race that could develop a political philosophy so arid in its cynical despair of any good in human nature forces itself vividly upon our notice. Guicciardini seems to glory in his disillusionment, and uses his vast intellectual ability for the analysis of the corruption he had helped to make incurable.

If one single treatise of that century should be chosen to represent the spirit of the Italian people in the last phase of the Renaissance, the historian might hesitate between the Principe of Machiavelli and the Ricordi politici of Guicciardini. The latter is perhaps preferable to the former on the score of comprehensiveness. It is, moreover, more exactly adequate to the actual situation, for the Principe has a divine spark of patriotism yet lingering in the cinders of its frigid science, an idealistic enthusiasm surviving in its moral aberrations; whereas a great Italian critic of this decade has justly described the Ricordi as Italian corruption codified and elevated to a rule of life.

Guicciardini is, however, better known as the author of the "Storia d'Italia", that vast and detailed picture of his country's sufferings between the years 1494 and 1532. Judging him by this masterpiece of scientific history, he deserves less commendation as a writer than as a thinker and an analyst. The style is prolix, precise but at the expense of circumlocution, the details as distinct as the main narrative. The whole tangled skein of Italian politics of an involved and stormy period is unravelled with patience and insight. The author is an impartial spectator, a cold and curious critic. This want of feeling impairs the interest of his history. He does not seem to be aware that he is writing a great historical tragedy from his own times. He takes as much pains on a petty war with Pisa as in probing the papacy. Whatever he touches, lies already dead on the dissecting table. He fails to understand the vigour of the forces contending in Europe for mastery; this is very noticeable in what he writes about the Reformation. The Storia d'Italia was still undoubtedly the greatest historical work that had appeared in the early modern era. It remains the solid monument of the Italian reason in the 16th century, the final triumph of the Florentine school of philosophical historians which included Machiavelli, Segni, Pitti, Nardi, Varchi, Francesco Vettori and Donato Giannotti.

Up to the year 1857 Guicciardini's reputation depended on the History of Italy, and on a few ill-edited extracts from his aphorisms. At that date his representatives, the counts Piero and Luigi Guicciardini, opened their family archives, and committed to Giuseppe Canestrini the publication of his memoirs, in ten volumes. The documents and finished literary work thus given to the world have thrown light on Guicciardini, as author and citizen. It has raised his reputation as a political philosopher into the first rank, where he now disputes the place of intellectual supremacy with his friend Machiavelli; but it has colored our moral judgment of his character and conduct with darker dyes. From the stores of valuable materials contained in those ten volumes, it is enough here to cite (1) the Ricordi politici, already noticed, consisting of about 220 maxims on political, social, and religious topics; (2) the observations on Machiavelli's Discorsi, which bring into relief the views of Italy's two great theorists on statecraft in the 16th century, and show that Guicciardini regarded Machiavelli somewhat as an amiable visionary or political enthusiast; (3) the Storia Fiorentina, an early work of the author, distinguished by its animation of style, brilliancy of portraiture, and liberality of judgment; and (4) the Dialogo del reggimento di Firenze, also in all probability an early work, in which the various forms of government suited to an Italian commonwealth are discussed with subtlety, contrasted, and illustrated from the vicissitudes of Florence up to the year 1494. To these may be added a series of short essays, entitled Discorsi politici, composed during Guicciardinis Spanish legation. Those who desire to gain an insight into the true principles and feelings of the men who made and wrote history in the 16th century will find it here far more than in the work designed for publication by the writer. Taken in combination with Machiavelli's treatises, the Opere inedite furnish a comprehensive body of Italian political philosophy before Fra Paolo Sarpi.

See Rosini's edition of the Storia d'Italia (10 vols., Pisa, 1819), and the Opere inedite, in 10 vols., published at Florence, 1857. A complete and initial edition of Guicciardini's works is now in preparation in the hands of Alessandro Gherardi of the Florence archives. Among the many studies on Guicciardini we may mention Agostino Rossi's Francesco Guicciardini e il governo Fiorentino (2 vols., Bologna, 1896), based on many new documents; Francesco de Sanctis's essay L'Uomo del Guicciardini, in his Nuovi Saggi critici (Naples, 1879), and many passages in P. Villari's Machiavelli (Eng. trans., 1892); Eugène Benoist's Guichardin, historien et homme du l'Italie au XVI siècle (Paris, 1862), and C. Gioda's Francesco Guicciardini e le sue opere inedite (Bologna, 1880) are not without value, but the authors had not had access to many important documents since published. See also Geoffroy's article Une Autobiographie de Guichardin d'après ses oeuvres inédites, in the Revue des deux mondes (1 February 1874).
