Attempted escape known as the Flight to Varennes, intercepted and returned to Paris.
On June 21, 1791, Marie Antoinette fled Paris with the royal family in an ill-fated escape known as the Flight to Varennes. The plan was to reach loyalist strongholds, but they were intercepted and returned to Paris by revolutionary forces. This incident not only undermined royal authority and public trust but also marked a critical point in the monarchy's decline, intensifying calls for the establishment of a republic and sealing their eventual fate during the Revolutionary Tribunal.
