Francisco Franco's quasi-fascist Falangist one-party state in Spain was officially neutral during World War II and survived the collapse of the Axis Powers. Franco's rise to power had been directly assisted by the militaries of Fascist Italy and Nazi Germany during the Spanish Civil War and had sent volunteers to fight on the side of Nazi Germany against the Soviet Union during World War II. After World War II and a period of international isolation, Franco's regime normalized relations with Western powers during the early years of the Cold War until Franco's death in 1975 and the transformation of Spain into a liberal democracy.
