The League of American Writers was an association of American novelists, playwrights, poets, journalists, and literary critics launched by the Communist Party USA (CPUSA) in 1935. The group included Communist Party members, and so-called "fellow travelers" who closely followed the Communist Party's political line without being formal party members, as well as individuals sympathetic to specific policies being advocated by the organization.
The League's policy objectives changed over time in accord with the shifting party line of the CPUSA. Beginning as an anti-fascist organization in 1935, the League turned to an anti-war position following the signing of the Nazi-Soviet Pact of 1939 and to a pro-war position after the German invasion of the Soviet Union in June 1941. The organization was prominent in the defense of Republican Spain during the Spanish Civil War and in providing financial and moral support to writers in need in the United States and internationally.
The organization was terminated in January 1943.
The League of American Writers was established by the First American Writers Congress, a gathering held from April 26–28, 1935. The organization was affiliated with the International Union of Revolutionary Writers (IURW) as well as the International Association of Writers for the Defense of Culture and was the American equivalent of the British League of Writers.
In an article in the magazine of the IURW, International Literature, League of American Writers member Alan Calmer noted that the new organization sprung from a decision made at the 1934 convention of the Communist Party's John Reed Clubs:
"The chief malady of the revolutionary culture movement was characterized at the second national conference of the John Reed Clubs in 1934 as the old malady of sectarianism.... Pointing to these handicaps, the delegates to the conference instructed their executive committee to take the initiative in sponsoring a broad conference of left-wing authors... A new organization committee was formed, which gradually involved more and more sympathetic writers into the leadership of the committee which issued the "Call for an American Writers Congress" at the beginning of 1935."
