The Abraham Lincoln Brigade (Spanish: Brigada Abraham Lincoln) was the name given to the 2,800 Americans who volunteered to fight for the Spanish Republic against the Nationalists in the Spanish Civil War.[1] The Americans were organized into several battalions (Lincoln Battalion, Washington Battalion, etc.) that were assigned to the XV International Brigade (XV Brigada Internacional), which was one of many such mixed brigades within the International Brigades.
