The Spanish Civil War was a civil war in Spain fought from 1936 to 1939. Republicans loyal to the left-leaning Second Spanish Republic, in alliance with anarchists, of the communist and syndicalist variety, fought against a revolt by the Nationalists, an alliance of Falangists, monarchists, conservatives and Catholics, led by a military group among whom General Francisco Franco soon achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as class struggle, a war of religion, a struggle between dictatorship and republican democracy, between revolution and counterrevolution, and between fascism and communism. It has been frequently called the "dress rehearsal" for World War II. The Nationalists won the war, which ended in early 1939, and ruled Spain until Franco's death in November 1975.
The war began after a pronunciamiento against the Republican government by a group of generals of the Spanish Republican Armed Forces, with General Emilio Mola as the primary planner and leader and having General José Sanjurjo as a figurehead.
