Progressive Party (United States, 1912)
The Progressive Party was a third party in the United States formed in 1912 by former President Theodore Roosevelt after he lost the presidential nomination of the Republican Party to his former protégé, incumbent President William Howard Taft. The new party was known for taking advanced positions on progressive reforms and attracting some leading reformers. After the party's defeat in the 1912 presidential election, it went into rapid decline, disappearing by 1918. The Progressive Party was popularly nicknamed the "Bull Moose Party" since Roosevelt often said that he felt "strong as a bull moose" both before and after an assassination attempt on the campaign trail.
People's Party (United States)
The People's Party (also known as the Populist Party or the Populists) was a agrarian political party in the United States. The Populist Party emerged in the early 1890s as an important force in the Southern United States and the Western United States, but the party collapsed after it nominated Democrat William Jennings Bryan in the 1896 United States presidential election. A rump faction of the party continued to operate into the first decade of the 20th century, but never matched the popularity of the party in the early 1890s.
