Secular Humanism became more prominent during the French Revolution. This philosophical stance emphasizes the importance of reason, ethics, and justice without reliance on religious beliefs. The movement emerged as an intellectual response to the long-standing dominance of the Catholic Church in French society. During the Enlightenment period preceding the Revolution, thinkers like Voltaire and Diderot propagated ideas challenging the authority of the Church. These Enlightenment ideas laid the groundwork for the secular humanist principles that would later gain traction. Revolutionary leaders such as Maximilien Robespierre and Jean-Paul Marat espoused secular values in their vision for a transformed society, advocating for the application of science and reason in the structuring of government and laws. The Declaration of the Rights of Man and of the Citizen (adopted on 26 August 1789) encapsulated many secular humanist principles; it emphasized equality, freedom of speech, and freedom from oppression. The Revolution's initial phase saw a concerted effort to separate the state from the Church, culminating in the Civil Constitution of the Clergy (passed on 12 July 1790). This decree redefined the role of the Catholic clergy, subordinating religious authority to the state. The Reign of Terror (1793-1794), though often associated with radical violence, also featured elements of secular humanist thought. The Committee of Public Safety promoted the Cult of Reason, an atheistic alternative to traditional religious practices. Festivals and other public ceremonies were held to honor reason, nature, and humanity instead of Christian figures and saints. However, secular humanism during the Revolution was not monolithic. Different factions held varying interpretations of how to implement secular ideas. Some revolutionaries favored a deistic approach, while others leaned more toward outright atheism. These ideological differences sometimes led to internal conflicts. By the end of the Revolution, secular humanism had left a lasting legacy in French society. The Napoleonic Code (enacted in 1804) reflected some of these principles by emphasizing rational legal frameworks and equality before the law. Though not all aspects of the Revolution were uniformly secular, the movement undeniably influenced the development of modern secular states and the spread of humanist values in European thought.
