The French Revolution, which lasted for ten years during the very late 18th century, took a great toll on religion. Prior to the French Revolution, France had been a Catholic country. During the Revolution, however, France began to war with its priests. In an attempt to buy their loyalty, the Revolutionaries dictated that the government would pay the salaries of the holy men. Eventually priesthood was banned and all Catholics quickly fled the country, unless they were already locked up in jail. Robespierre soon instated the Cult of Reason as a religion and replaced the calendar. The new French calendar would have 12 months with 30 days each and ten days per week. To make the number of days on the new calendar match the number of days in a year, five days were added, each one a national feast. This crazy calendar, along with the accompanying Cult of Reason, were discarded when Napoleon rose to power and realized that nobody actually used the new calendar. Once again, France would follow the Catholic tradition.
