Noah moved to New York, where he founded and edited
The National Advertiser,
The New York Enquirer (later merged into
The Courier and Enquirer),
The Evening Star, and
The Sunday Times newspapers.
In 1819, Noah's most successful play,
She Would Be a Soldier, was produced. That play has since established Noah as America's first important Jewish American writer.
She Would Be a Soldier is now included in college level anthologies.In 1825, with virtually no support from anyone-not even his fellow Jews- in a precursor to modern Zionism, he tried to found a Jewish "refuge" at Grand Island in the Niagara River, to be called "Ararat," after Mount Ararat, the Biblical resting place of Noah's Ark. He had brought with him a cornerstone which read "Ararat, a City of Refuge for the Jews, founded by Mordecai M. Noah in the Month of Tishri, 5586 (September, 1825) and in the Fiftieth Year of American Independence." Noah also shared the belief among various others that some of the Native American Indians were from the Lost Tribes of Israel, from which he wrote the
Discourse on the Evidences of the American Indians being the Descendants of the Lost Tribes of Israel.
In his ''Discourse on the Restoration of the Jews'' Noah proclaimed his faith that the Jews would return and rebuild their ancient homeland and called on America to take the lead in this endeavor. On September 2, soon after arriving in Buffalo from New York, thousands of Christians and a smattering of Jews assembled for a historic event. Noah led a large procession,headed by Masons, a New York militia company, and municipal leaders paraded to St. Paul's Episcopal church . Here, there was a brief ceremony- including a singing of the psalms in Hebrew- the cornerstone was laid on the communion table, and the new proclamation establishing the refuge was read. "Proclamation — day ended with music, cannonade and libation. 24 guns, recessional,masons retired to the Eagle Tavern, all with no one ever having set foot on Grand Isle." This was the beginning and the end of Mordecai Noah's venture: he lost heart and returned to New York a couple days later without once having set foot on the island. The cornerstone was taken out of the audience chamber of the church and laid against the back of the building. It is now on permanent display at the Buffalo Historical Society in Buffalo, NY.
From 1827-1828, Noah led New York City's Tammany Hall political machine.
He was a staunch supporter of slavery. He worried that emancipation would threaten the whole country's safety.
MacArthur Award-winning cartoonist Ben Katchor fictionalized Noah's scheme for Grand Island in his
The Jew of New York. Noah is also a minor character in Gore Vidal's 1973 novel
Burr.
The modern edition of Noah's writings is
The Selected Writings of Mordecai Noah edited by Michael Schuldiner and Daniel Kleinfeld, and published by Greenwood Press.
American Conservative rabbi Henry Noah is a direct descendant.
