Spanish Civil War ('36-'39). The outbreak of civil war in Spain in 1936 was viewed in Europe and the United States as an ideological struggle between the forces of fascism, led by General Francisco Franco, and the forces of republicanism, called Loyalists.
By mid-1924 many Spaniards were sick of the fighting. So too was Spain's dictator, Miguel Primo de Rivera. Spain had spent a lot of money and was gaining nothing in wealth from Morocco, and Primo de Rivera complained about the tens of thousands of men killed in the war.
