Panagiotis Kanellopoulos or Panayotis Kanellopoulos (Greek: Παναγιώτης Κανελλόπουλος; 13 December 1902 – 11 September 1986) was a Greek writer, politician and Prime Minister of Greece. He was the Prime Minister of Greece deposed by the Greek military junta of 1967–1974.
The Metapolitefsi (Greek: Μεταπολίτευση, romanized: Metapolítefsi, IPA: [metapoˈlitefsi], "regime change") was a period in modern Greek history from the fall of the Ioannides military junta of 1973–74 to the transition period shortly after the 1974 legislative elections.
The metapolitefsi was ignited by the liberalisation plan of military dictator Georgios Papadopoulos, which was opposed by prominent politicians such as Panagiotis Kanellopoulos and Stephanos Stephanopoulos, and halted by the massive Athens Polytechnic uprising against the military junta. The counter coup of Dimitrios Ioannides, and his coup d'etat against President of Cyprus Makarios III, which led to the Turkish invasion of Cyprus, brought the dictatorship down.
