The Catholic Church lose power during the French Revolution. Instead of the Catholic Church, a new creation was introduced... The Cult of the Supreme Being. This cult was founded by Maximilian Robespierre, the head of the Jacobins and a major figure in the Reign of Terror. However, after the Revolution ended, the Catholic Church regained much of its former power. This was, in part, due to the fact that many of the "common" people in France were firm followers in the Church, even throughout the Revolution, and after it, when the Church was re-named as the state "religion," they went happily back into their old way of life, with the Catholic Church.
