Hollywood Anti-Nazi League

The Hollywood Anti-Nazi League (later known as the American Peace Mobilization) was founded in Los Angeles in 1936 by Soviet agent Otto Katz and others with the stated purpose of organizing members of the American film industry to oppose fascism and Nazism. It was run by the American popular front, and it attracted broad support in Hollywood from both members and nonmembers of the Communist Party USA (CPUSA). It ceased all anti-Nazi activities immediately upon the signing of the Molotov–Ribbentrop Pact in August 1939.
