What is the name of the second estate of French society at the end of the 18th century?

In France, like other states in the Middle Ages, there was a special hierarchy of citizens, which was formed on the basis of feudal relations. At the highest level were the clergy, who played a consolidating role in the state. The nobles belonged to the second estate. They provided massive support to the king. At the lowest level were people from the unprivileged strata. The nobles were considered an authoritative class, since they entered the feudal ladder and occupied far from the last place on it.
