The Greek military junta of 1967–1974, alternatively "The Regime of the Colonels" (Greek: Το καθεστώς των Συνταγματαρχών, To kathestos ton Syntagmatarhon), or in Greece "The Junta", Greek Χούντα, and "The Seven Years" (Greek: Η Επταετία, I eptaetía) are terms used to refer to a series of right-wing military governments that ruled Greece from 1967 to 1974. Rule by the military started in the morning of 21 April 1967 with a coup d'état led by a group of colonels of the Greek military, and ended in July 1974. The brutal suppression of the Athens Polytechnic uprising on 17 November 1973 sent shockwaves through the regime, and a counter-coup established Brigadier Dimitrios Ioannidis as dictator. On 20 July 1974, as Turkey invaded the island of Cyprus, the regime of the Colonels collapsed. A democratic and republican constitution was promulgated in Greece on 11 June 1975 following a referendum which abolished the monarchy.
