Context: Francoist Spain (Spanish: España franquista), or the Francoist dictatorship (dictadura franquista), was the period of Spanish history between 1939 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title Caudillo. After his death in 1975, Spain transitioned into a democracy. During this time period, Spain was officially known as the Spanish State (Estado Español).

The nature of the regime evolved and changed during its existence. Months after the start of the Spanish Civil War in July 1936, Franco emerged as the dominant rebel military leader and was proclaimed head of state on 1 October 1936, ruling a dictatorship over the territory controlled by the Nationalist faction. The 1937 Unification Decree, which merged all parties supporting the rebel side, led to Nationalist Spain becoming a single-party regime under the FET y de las JONS. The end of the war in 1939 brought the extension of the Franco rule to the whole country and the exile of Republican institutions. The Francoist dictatorship originally took a form described as "fascistized dictatorship", or "semi-fascist regime", showing clear influence of fascism in fields such as labor relations, the autarkic economic policy, aesthetics, and the single-party system. As time went on, the regime opened up and became closer to developmental dictatorships, although it always preserved residual fascist elements.
