French Constitution of 1793

The Constitution of 1793 (French: Acte constitutionnel du 24 juin 1793), also known as the Constitution of the Year I or the Montagnard Constitution, was the second constitution ratified for use during the French Revolution under the First Republic. Designed by the Montagnards, principally Maximilien Robespierre and Louis Saint-Just, it was intended to replace the constitutional monarchy of 1791 and the Girondin constitutional project.
