Groups of foreign volunteers who fought on the Republican side against the Nationalist forces in the Spanish Civil War (193639).
So-called because their members initially came from some 50 countries, the International Brigades were recruited, organized, and directed by the Comintern , with headquarters in Paris. The U.S. contingent called itself the Abraham Lincoln Batallion. Many of the mostly young recruits were communists before they became involved in the conflict; more joined the party during the course of the war. The total number of volunteers reached about 60,000. The brigades were formally withdrawn from Spain late in 1938.
