The Spanish Civil War started in July 1936 with the military coup leaded by General Franco, which started a rebellion against the democratically elected Republican goverment. Since the establishment of a Republic and the abolition of the monarchy in 1931, mostly left-wing parties and progressisf leaders had won the elections.
The most conservative sectors of the army followed the fascist general Franco who, during the war, received the support of Hitler and Mussolini, specially, of their aviation military units.
