 The current Third Hellenic Republic () was declared in 1974 during the "Metapolitefsi" (Greek, "regime change"), after the end of the Regime of the Colonels which had controlled Greece since the coup d'état of 21 April 1967.The Junta had already held a staged referendum to abolish the monarchy on 29 July 1973, and passed a new Constitution which established a presidential republic (with junta leader Georgios Papadopoulos as President).This short-lived attempt at controlled democratization was ended by the hardliners under Brigadier Dimitrios Ioannides, who overthrew Papadopoulos in November 1973 in the aftermath of the Athens Polytechnic uprising.
