The fall of the Greek military junta in 1974 ended authoritarian rule and created the political conditions necessary for democratic reconstruction. The transition, known as the Metapolitefsi, required a new legal framework to replace the institutions of the dictatorship and formally establish a republican form of government.
The Fifth Revisionary Hellenic Parliament drafted and adopted the Constitution of Greece in 1974–1975. Adopted on 9 June 1975 and entering into force on 11 June 1975, the document established the legal foundations of the Third Hellenic Republic, defining the structure of government, civil liberties, and state institutions.
The constitution has served as the supreme law of Greece since 1975, providing institutional stability through successive governments. It has been amended four times—in 1986, 2001, 2008, and 2019—adapting to evolving political, social, and European integration demands while maintaining its core republican and democratic character.
