On 20th June Louis XVI attempted to escape to the eastern frontier, leaving behind a justification of his position which made it clear he wished to revert to the privileges of the ancien regime. Louis was quickly caught and returned to Paris where, on July 16th, a public demonstration on the Champ de Mars began signing a petition for the king's abdication and the formation of a Republic. The Mayor of Paris and Marquis de LaFayette sent troops to disperse the crowd. Shots were fired and some 50 died in the first reactionary act by the new powers.
