The Spanish transition to democracy, known in Spain as la Transición (la tɾansiˈθjon; "the Transition") or la Transición española ("the Spanish Transition"), is a period of modern Spanish history encompassing the regime change that moved from the Francoist dictatorship to the consolidation of a parliamentary system, in the form of constitutional monarchy under Juan Carlos I.
According to scholars, the democratization process began after the death of the dictator Francisco Franco, in November 1975. Historians disagree on the exact date the transition was completed: some say it ended after the 1977 general election, while others place it later, when the 1978 Constitution was approved. Others suggest it ended with the failure of the 1981 attempted coup d'état. At its latest, the Transition is said to have ended with the first peaceful transfer of executive power, after the victory of the Spanish Socialist Workers' Party (PSOE) in the 1982 general election.
While often cited as a paradigm of peaceful, negotiated transition, political violence during the Spanish transition was far more prevalent than during the analogous democratization processes in Greece or Portugal, with the emergence of separatist, revolutionary, fascist and vigilante terrorist groups.
General Francisco Franco came to power in 1939, following the Spanish Civil War (1936–1939), and ruled as a dictator until his death in 1975. In 1969, he designated Prince Juan Carlos, grandson of Spain's most recent king, Alfonso XIII, as his official successor. For the next six years, Prince Juan Carlos initially remained in the background during public appearances and seemed ready to follow in Franco's footsteps. Once in power as King of Spain, however, he facilitated the development of a constitutional monarchy as his father, Don Juan de Borbón, had advocated since 1946.
The transition was an ambitious plan that counted on ample support both within and outside of Spain. Western governments, headed by the United States, now favoured a Spanish constitutional monarchy, as did many Spanish and international liberal capitalists.
