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.
Georgios Zoitakis
Following the failure of King Konstantínos II's counter-coup on 13 December 1967 and the subsequent flight of the Royal Family to Italy, Zoitakis was sworn in as Regent for the absent King. He held this post until 21 March 1972, when he was replaced by the junta's principal leader, Prime Minister Georgios Papadopoulos. At the same time, he was retired from the Army with the rank of full general. On 1 June 1973, Papadopoulos would abolish the monarchy and declare himself President of a new republic.
After Greece's return to democracy, in 1975 Zoitakis, along with the other junta leaders, was tried and convicted to life imprisonment for high treason. He remained in prison for 13 years until 1988, when he was released, due to deteriorating health. A pardon plea was rejected in 1991, and he remained confined to his residence in Athens until his death in 1996.
