The Declaration of the Rights of Man abolished the three estates which had kept people unequal in the eyes of the law.
Step-by-step explanation:
Under the old regime (or "Ancien Régime," to put it in French), was full of inequality. Under the Ancien Régime, the aristocracy in France enjoyed much rank and privilege. Being a member of the "Second Estate" (the nobility or aristocracy) meant being exempt from most taxes that supported the nation. The 98% of the population that made up the "Third Estate" paid the costs of running a kingdom that supported the king and the aristocracy. (Note: The "First Estate," or clergy, included high-ranking members that were essentially aristocrats, as well as low-ranking persons like parish priests who were more like commoners.)
