Battle of Teruel in the context of "International Brigades"

The International Brigades (Spanish: Brigadas Internacionales) 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.

The headquarters of the brigade was located at the Gran Hotel, Albacete, Castilla-La Mancha. They participated in the battles of Madrid, Jarama, Guadalajara, Brunete, Belchite, Teruel, Aragon, and the Ebro. Most of these ended in defeat. For the last year of its existence, the International Brigades were integrated into the Spanish Republican Army as part of the Spanish Foreign Legion. The organisation was dissolved on 23 September 1938 by Spanish Prime Minister Juan Negrín in a vain attempt to get more support from the liberal democracies on the Non-Intervention Committee.
