Third National Assembly at Troezen

The Third Greek National Assembly at Troezen (Template:Lang-el) convened in 1827.

Its purpose was to establish a stable, liberal and working Government for Greece as it existed at that time. It unanimously elected John Capodistria as Governor of Greece for a seven-year term and it also approved by vote of the Political Constitution of Greece. It established key principles in Greek Constitutional history which remain to this day, such as the statement Sovereignty lies with the people; every power derives from the people and exists for the people.

This Constitution consisted of 150 articles. It established a strict separation of powers, vesting the executive power to the Governor and assigning to the body of the representatives of the people, named Boule, the legislative power. The Governor only had a suspending veto on the bills, and lacked the right to dissolve the Parliament. He was inviolable, while the Secretaries of the State, in other words the Ministers, assumed the responsibility for his public actions (thus introducing into the text of the 1827 Constitution the first elements of the so called parliamentary principle).
