Before French revolution, king Louis XVI and Marie Antoinette, was the first estates from old Regime.
Tennis Court Oath
The first and third estates wasted lots and lots of money, and they waste food. It was not true that Marie Antoinette said that "let them eat cake" but it is trying to say that she did not understanding the poor about third estates.
Staying at the Jail for protection
National Assembly was already been made before French Revolution. They did not like the King and Queen because they did not care about people who is starving from food and they just only enjoyed the parties. The leader of the National Assembly was Maximillian Robespierre.
Please do not kill me
Maximillian Robespierre, gather up the people and tried to make the Tennis court Oath, so the king will listening to them, but Louis XVI thought that if he use his force with military to break up than it will be more faster to suppress in Tennis Court demonstration. But it was different this time the people was scared so they find weapons from their houses and from prison.
So Louis XVI and Marie Antoinette was going to get killed so they ask parliament to make them safe, not to die but parliament were smart so they sent them to the jail. So they have them controlled so by that time the king and queen did not have lot of authority and serving by the people. Because of this people say that Marie Antoinette's hair got white
After the Guerilla French Revolution, they used Guillotine to executed the King Louis XVI from the French revolution they made Declaration of the rights of Man. They used it to keeping Liberty, Equality, and fraternity for every French people.
