Serment du Jeu de paume
During the French Revolution (from July 1789 to September 1791) a National Constituent Assembly () was formed when representatives assembled at the only location available – a tennis court – and swore the Tennis Court Oath on June 20, 1789, promising that they would not adjourn until they had drafted a new constitution for France. Louis XVI recognized the validity of the National Constituent Assembly on June 27, 1789.
