The French Constitution of 1791 (Constitution française du 3 septembre 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 French Revolution was adopting constitutionality and establishing popular sovereignty. Following the Tennis Court Oath, the National Assembly began the process of drafting a constitution as its primary objective. The Declaration of the Rights of Man and of the Citizen, adopted on 26 August 1789 eventually became the preamble of the constitution adopted on 3 September 1791. The Declaration offered sweeping generalizations about rights, liberty, and sovereignty. A twelve-member Constitutional Committee was convened on 14 July 1789 (coincidentally the day of the Storming of the Bastille). Its task was to do much of the drafting of the articles of the constitution. It included originally two members from the First Estate (Champion de Cicé, Archbishop of Bordeaux and Talleyrand, Bishop of Autun); two from the Second (the comte de Clermont-Tonnerre and the marquis de Lally-Tollendal); and four from the Third (Jean Joseph Mounier, Abbé Sieyès, Nicholas Bergasse, and Isaac René Guy le Chapelier). Many proposals for redefining the French state were floated, particularly in the days after the remarkable sessions of 4–5 August 1789 and the abolition of feudalism. For instance, the Marquis de Lafayette proposed a combination of the American and British systems, introducing a bicameral parliament, with the king having the suspensive veto power over the legislature, modeled to the authority then recently vested in the President of the United States. The main controversies early on surrounded the issues of what level of power to be granted to the king of France (i.e.: veto, suspensive or absolute) and what form would the legislature take (i.e.: unicameral or bicameral).
