Georgios Papadopoulos
Georgios Papadopoulos (; ; 5 May 1919 – 27 June 1999) was the head of the military coup d'état that took place in Greece on 21 April 1967, and leader of the junta that ruled the country from 1967 to 1974. He held his dictatorial power until 1973, when he was himself overthrown by his co-conspirator Dimitrios Ioannidis.
Metapolitefsi
In September 1973, Georgios Papadopoulos, the head of the military junta that took power in 1967, initiated an attempt at "metapolitefsi" or process of liberalisation, aiming to legitimize his government and rehabilitate its image as an international, and especially European, pariah after six years of dictatorship during which he appointed himself to a multitude of high-echelon government positions including Regent, Prime Minister, Minister for Defence, and Minister for the Interior. These excesses had the effect of further undermining his credibility and the seriousness of his regime both at home and abroad. Feeling confident of his grasp on power he requested the resignation of the 13 military men in his cabinet and appointed Spyros Markezinis as Prime Minister of Greece, entrusting him with the task of leading Greece to parliamentary rule. Papadopoulos however proposed a constitution that accorded far greater powers to the President of Greece (a position Papadopoulos also held) than those of the Parliament.
