Louis XVI and Marie Antoinette live comfortably in Versailles. The Old Regime puts royalty on the highest status.
The peasants which were in the Third Estate paid all the taxes and couldn't afford bread since the price of wheat shot up.
After being locked out of a Estates-General meeting, the third estate renamed themselves the "National Assembly" and began drafting a constitution "The Declaration of the Rights of Man" during the Tennis Court Oath.
Robespierre seized power, beginning his Reign of Terror. He actively used the guillotine to silence citizens who disagreed with his policies.
People were not happy with Robespierre and some still sided with the monarchy.
After Robespierre is executed, Napoleon got into power soon after in a coup d'etat.
