1. there were many inequalities that contributed to the French Revolution, the first group was the clergy, the second estate was made up of nobles, and the third estate was the vast majority of the people living in France. One inequality dealt with taxation. The first two estates didn't have to pay most of the taxes.

2. The impact was so big that eventually slaves were freed, because the declaration stated that “All men and women are born and remain free in equal rights”

3. France was broke. The nobility refused to pay more taxes, and the peasants simply couldn't. Even the opulent King Louis XVI, fonder of hunting and locksmithing than governing, recognized that a crisis loomed, they wanted to change between the ruler and the governs to help rebuild their political and economic power.

4. The biggest cause behind the French Revolution was a widespread discontent with the French monarchy and the poor economic policies of King Louis XVI.
