The International Brigades were volunteer soldiers organized by the Communist International to assist the Popular Front government of the Second Spanish Republic during the Spanish Civil War. The International Brigades existed for two years, from 1936 until 1938. It is estimated that during the entire war, there were some 32,000 Brigaders, yet at no single moment were there more than 18,000 actually deployed. Beyond the Spanish Civil War, "International Brigades" is also sometimes used interchangeably with the term foreign legion in reference to military units comprising foreigners who volunteer to fight in the military of another state, often in times of war.
