The People's Party of the late 19th century United States is considered to be "one of the defining populist movements"; its members were often referred to as the Populists at the time. Its radical platform included calling for the nationalisation of railways, the banning of strikebreakers, and the introduction of referendums. The party gained representation in several state legislatures during the 1890s, but was not powerful enough to mount a successful presidential challenge. In the 1896 presidential election, the People's Party supported the Democratic Party candidate William Jennings Bryan; after his defeat, the People's Party's support declined. Other early populist political parties in the United States included the Greenback Party, the Progressive Party of 1912 led by Theodore Roosevelt, the Progressive Party of 1924 led by Robert M. La Follette, Sr., and the Share Our Wealth movement of Huey P Long in 1933–1935. In Canada, populist groups adhering to a social credit ideology had various successes at local and regional elections from the 1930s to the 1960s, although the main Social Credit Party of Canada never became a dominant national force.
