The Greek national assemblies (Greek: Εθνοσυνελεύσεις) are representative bodies of the Greek people. During and in the direct aftermath of the Greek War of Independence (1821–1832), the name was used for the insurgents' proto-parliamentary assemblies. Thereafter, the term has been used for a number of extraordinary assemblies chiefly in regard to changes in the Constitution and the form of government of Greece.
Their purpose was the drafting of the first constitutions by which the nascent Greek state was to be governed, and elect the parliamentary and executive bodies to lead the struggle for liberation.
These were convened decide on issues regarding the form of government and promulgate new constitutions.
