Today in Labor History February 21, 1937: The League of Nations banned foreign nationals from volunteering in the Spanish Civil War. Nevertheless, thousands from Britain, the U.S. and other countries came to Spain and joined the Republicans in the fight against Franco and fascism. Altogether, over 59,000 international volunteers supported the anti-fascist cause, along with over 3,000 soviet “technicians.” Roughly 500,000 soldiers and civilians died in the war. The antifascist republican forces lost, leading to a 40-year fascist dictatorship.
One of the battalions of American volunteers was named the Tom Mooney Machine-Gun Company, after the anarchist IWW member Tom Mooney, who was framed for the 1916 Preparedness Day bombing in San Francisco. It was led by Oliver Law, a communist, and the first black man known to have commanded white U.S. troops. Law was from West Texas and had worked as a stevedore. Due to his skill, Law quickly rose in the ranks of the Republican army. However, he died on July 9, 1937, as he led an attack on Mosquito Crest.
