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.
Andreas Papandreou
The Panhellenic Socialist Movement (PASOK), which he founded and led, was the first non-communist political party in Greek history with a mass-based organization, introducing an unprecedented level of political and social participation in Greek society. In a poll conducted by Kathimerini in 2007, 48% of those polled called Papandreou the "most important Greek Prime Minister". In the same poll, the first four years of Papandreou's government after Metapolitefsi were voted as the best government Greece ever had.
