Spanish Civil War [SEP] Introduction
The Spanish Civil War () was a civil war in Spain fought from 1936 to 1939. Republicans loyal to the left-leaning Popular Front government of the 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 traditionalists, 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.
