Anti-establishment ideas fermented in 18th-century France in part due to the country's relative egalitarianism. While less liberal than England during the same period, the French monarchy never approached the absolutism of the eastern rulers in Vienna, Berlin, St. Petersburg, and Constantinople in part because the country's traditional development as a decentralized, feudal society acted as a restraint on the power of the king. Different social classes in France each had their own unique set of privileges so that no one class could completely dominate the others.
