The Greek military junta collapses, and former Prime Minister Konstantinos Karamanlis is invited to lead the new government, beginning Greece's metapolitefsi era.

The Greek junta or Regime of the Colonels was a right-wing military junta that ruled Greece from 1967 to 1974. On 21 April 1967, a group of colonels overthrew the caretaker government a month before scheduled elections which Georgios Papandreou's Centre Union was favoured to win.

Konstantinos G. Karamanlis was a Greek statesman who was the four-time Prime Minister of Greece and two-term president of the Third Hellenic Republic, serving in the former role from 1955 to 1963 and from 1974 to 1980. A towering figure of Greek politics, his political career spanned portions of seven decades, covering much of the latter half of the 20th century.

The Metapolitefsi 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.
