"In Spain there was a constitutional monarchy from 1917 until 1923, then a military dictatorship under Primo de Rivera until 1930, then a republic that drifted steadily to the Left, culminating in the formation of the Popular Front coalition, which included both Communists and Socialists. After a bitter three-year civil war initiated in 1936 by a group of army officers and supported by the parties of the National Front, General Francisco Franco established himself as dictator, the beneficiary not only of German and Italian intervention but also of the debilitating 'civil war within the civil war' between the various factions of the Left."
