The People's Party, also known as the Populist Party or the Populists, was an agrarian-populist political party in the United States. For a few years, 1892–96, it played a major role as a left-wing force in American politics. It was merged into the Democratic Party in 1896; a small independent remnant survived until 1908. It drew support from angry farmers in the West and South and operated on the left-wing of American politics. It was highly critical of capitalism, especially banks and railroads, and allied itself with the labor movement.
