The Spanish Civil War , widely known in Spain simply as The Civil War or The War , took place from 1936 to 1939 and was fought between the Republicans, who were loyal to the democratic, left-leaning Second Spanish Republic, and the Nationalists, a falangist group led by General Francisco Franco. The Nationalists won, and Franco then ruled Spain for the next 36 years, from April 1939 until his death in November 1975.
