Spain, 1981 — military coup attempt

Spain (ESP)Southern Europe, EuropeFebruary 23, 1981

Event Summary

On 23 February 1981, in an event known in Spain as 23-F, right-wing Francoist officers of the Civil Guard and military attempted a coup to halt Spain's young democracy, five years after the death of the dictator Francisco Franco. At around 6:23 in the evening, Lieutenant Colonel Antonio Tejero, at the head of some 200 armed Civil Guards, burst into the Congress of Deputies in Madrid and held the entire government and parliament hostage at gunpoint during the live televised investiture vote for a new prime minister. Simultaneously, General Jaime Milans del Bosch declared a state of emergency and sent tanks into the streets of Valencia.

The plotters expected King Juan Carlos to endorse a military government, but instead the King, as commander in chief, went on television in the early hours of 24 February in his uniform to denounce the coup and order the armed forces to uphold the constitution. Deprived of royal legitimacy and military support, the coup collapsed; Tejero surrendered the next day. The failure marked the last serious attempt to reverse Spanish democracy and consolidated the monarchy's legitimacy.
