The concept of natural rights played a crucial role during the French Revolution. Rooted in Enlightenment thought, natural rights are seen as inherent and inalienable rights that every human possesses regardless of their social status or nationality. Philosophers like John Locke and Jean-Jacques Rousseau were instrumental in popularizing these ideas. The Declaration of the Rights of Man and of the Citizen (adopted on 26 August 1789) is one of the key documents of the French Revolution that embodies the concept of natural rights. It asserts that "men are born and remain free and equal in rights" (Article 1). This declaration was a direct challenge to the established social and political order of the Ancien Régime, which was characterized by a rigid hierarchical structure and extensive privileges for the nobility and clergy. Several articles within the Declaration directly address natural rights. For instance, Article 2 states that the aim of political association is the preservation of natural and imprescriptible rights such as liberty, property, security, and resistance to oppression. These principles were revolutionary in that they implied that all citizens were to have a say in governance, opposed to traditional monarchical rule. The influence of natural rights extended beyond France. The ideas propagated by the Declaration inspired numerous other movements and declarations. An example includes the Haitian Revolution, where enslaved Africans fought for their liberation, drawing heavily on the rhetoric of universal natural rights. Natural rights also had a significant impact on the various revolutionary reforms. The National Assembly passed numerous decrees aimed at dismantling feudal privileges (such as the abolition of serfdom and feudal dues on 4 August 1789) and establishing equality before the law. These reforms attempted to enshrine the principles of natural rights into law, although the actual implementation was often fraught with challenges and inconsistencies. Reactions to the assertion of natural rights were mixed. While they galvanized revolutionaries, they also alarmed many traditionalists and monarchists. The idea that rights were inherent and could not be granted or revoked by rulers posed a direct threat to the established order. Consequently, the defense of these natural rights often became a central justification for revolutionary actions and policies. In conclusion, natural rights were a cornerstone of the ideological foundation of the French Revolution. Their assertion and implementation reflected the broader Enlightenment ideals that sought to redefine the relationship between the state and its citizens, fundamentally altering the course of French (and global) history.
