During the French Revolution, two separate belief systems were developed in an effort to replace Christianism. For one, Robespierre created the Cult of the Supreme Being, a kind of deism. On the other hand, there was the Cult of Reason, aligned with atheism, individual freedom and the ideals of the Enlightenment: liberté, egalité and fraternité (liberty, equality and fraternity).
On November 10, 1793, the Cult of Reason organized a celebration in the Cathedral Notre-Dame de Paris, which was renamed Notre-Dame de la Raison, or Our Lady of Reason, for the occasion.
Fête de la Raison ("Festival of Reason"), Notre Dame, Paris.
