Socialist Workers Party (United States)
political party in the United States
The Socialist Workers Party (SWP) is a socialist party in the United States. SWP was created in 1938 after Communist Party USA expelled supporters of Leon Trotsky (against Joseph Stalin).
For most of its history, SWP was the largest Trotskyist organization in the US. In the 1980s, the SWP turned from Trotskyism towards Castroism. Since the 2000s, SWP has supported Zionism.
In the 1960s and 1970s, SWP and its youth wing, the Young Socialist Alliance, were together the 3rd-largest socialist organizations, below the Communist Party USA and Students for a Democratic Society. SWP suffered many splits and its membership declined. The modern SWP is smaller than its progeny, such as the Trotskyist Socialist Alternative and the Marxist-Leninist Party for Socialism and Liberation.
SWP focuses much of its energy on distributing The Militant, a socialist weekly, selling Pathfinder Press books, and running candidates on the SWP ballot line.
