The 1921 New York City mayoral election took place on November 8, 1921, resulting in a victory for Democratic Party candidate John Francis Hylan.[1]
The major candidates included New York City mayor and Democratic Party candidate John Hylan who stood for re-election, Manhattan borough president and Republican Party candidate Henry Curran, and the Socialist Party candidate Jacob Panken. Hylan was the son of an Irish-Catholic immigrant and affiliated with Tammany Hall machine politics. Curran had run as a coalition candidate for the Republican factions. Panken had run a progressive campaign and gained support from Milwaukee mayor Daniel Hoan, but failed to generate the same level of support as the Socialist candidate from the prior election, Morris Hillquit.[2]
In the primary election for mayor, Henry Curran heavily defeated Fiorello H. La Guardia, president of the board of aldermen.
