the royal family leaves Paris and escapes to Austria because they feel as though they are in danger from the mob of angry peasants. This is important because it shows that king Luois and queen Marie Antoinette have lost faith in the French people.
The royal family is stopped by a guard at an outpost. The guard asks them to step out of the carriage suspecting it to be the Queen and King. Once Marie Antoinette and King Louis found out they are then deported back to Paris. This is important because now the French people see their king and queen as traitors.
King Louis is forced to sign the constitution of 1791. The Royal couple is then arrested and imprisoned. Louis is convicted of treason and on January 1 he is executed. Nine months later Marie Antoinette is also convicted of treason and on October 16 she is also executed.
