The Constitution of Greece ( / Sýntagma), was created by the Fifth Revisional Parliament of the Hellenes and entered into force in 1975. It has been revised three times since, most significantly in 1986, and also in 2001 and in 2008. The Constitutional history of Greece goes back to the Greek War of Independence (1821-1832), during which the first three revolutionary Greek constitutions were adopted. Syntagma Square (Plateia Syntagmatos) in Athens is named after the first constitution adopted in the modern Greek State.
