After the American Revolution, France was declining in the economy. King Louis XVI and his wife, Marie Antoinette, continued to spend money even though France was suffering as a whole. As a result, the country's debt increased, harvests were failing, heavy taxes were hard to ignore, etc.
With the French Revolution, King Louis XVI's character weakened and he became more hostile to the country. When he dismissed Jacques Necker, his finance general, this decision sparked the invasion of the Bastille. If Louis hadn't dismissed Necker and his ideas regarding reforms, the struggle would've been resolved
French society followed the Estates System where they were classified as either nobility or peasants. The First Estate consisted of the Roman Catholic Church clergy. They were 1% of the population and controlled 5-10% of the lands. The Second Estate was the nobility. They were 2% of the population and controlled 25% of the lands. The Third Estate was the peasants. They were 97% of the population and had no voice in significant matters
The Third Estate changed its name to the National Assembly, a French Parliament constructed by the class. When they were locked out of their assembly hall for a meeting, they moved their location to a tennis court. The Tennis Court Oath was an agreement where each representative wouldn't leave the court without developing a new French constitution
French citizens stormed the Bastille on July 14, 1789. The Bastille was a royal prison that symbolized the tyranny of the Bourbon monarchs (ie King Louis XVI). They stole the ammunition that was housed there in order to end King Louis XVI's regime and gain momentum of the Revolution
Émigrés were Frenchman, most aristocrats, who left France in order to seek foreign help and restore the old French government. As a result, they were marked traitors, sent out a death sentence, and took away their property
