Lieutenant-Colonel Antonio Tejero led 200 armed Civil Guard officers into the Congress of Deputies during the vote to elect a Prime Minister. The officers held the parliamentarians and ministers hostage for 18 hours, during which time King Juan Carlos I denounced the coup in a televised address, calling for rule of law and the democratic government to continue. Though shots were fired, the hostage-takers surrendered the next morning without killing anyone. Pic. | |||
