French Constitution of 1791
The short-lived French Constitution of 1791 was the first written constitution in France, created after the collapse of the absolute monarchy of the Ancien Régime. One of the basic precepts of the revolution was adopting constitutionality and establishing popular sovereignty.
United States Constitution
The Articles of Confederation and Perpetual Union was the first constitution of the United States. It was drafted by the Second Continental Congress from mid-1776 through late 1777, and ratification by all 13 states was completed by early 1781. The Articles of Confederation gave little power to the central government. The Confederation Congress could make decisions, but lacked enforcement powers. Implementation of most decisions, including modifications to the Articles, required unanimous approval of all thirteen state legislatures.
