Revolutionary Surveillance Committees, also known as "Comités de surveillance révolutionnaire," were established during the French Revolution to monitor and report on suspected counter-revolutionary activities. Created in 1793, these committees were intended to identify and eliminate threats to the new republican government. Initially, the National Convention mandated the formation of one or more committees in each commune (the smallest administrative unit in France) and each section within larger cities. The committees were composed of citizens who were often zealous supporters of the Revolution. Their primary task was to oversee the surveillance of both public and private spaces, ensuring adherence to revolutionary ideals. They had the authority to issue certificates of patriotism to individuals deemed loyal to the Revolutionary cause. This certification was essential for participating in various civic activities and avoiding persecution. Members of the Surveillance Committees were responsible for conducting inquiries and investigations into alleged anti-revolutionary conduct. They gathered intelligence through informants, house searches, and intercepting correspondence. The committees reported findings to the Revolutionary Tribunal, a court established to try political offenders. The Tribunal had the power to condemn suspects to severe penalties, including imprisonment and execution. Furthermore, these committees played a significant role in the implementation of the Law of Suspects (passed on 17 September 1793), which widened the definition of counter-revolutionary activities to include a broad range of behaviors and associations. Under this law, individuals could be arrested based on mere suspicion or accusation by another citizen. The pervasive influence of these Surveillance Committees fostered an atmosphere of fear and suspicion. Relations between neighbors and even family members were strained as the risk of being denounced loomed large. However, the committees' actions were justified by many revolutionaries as a necessary means to safeguard the Republic from internal enemies. By 1795, with the fall of the Jacobin regime and the end of the Reign of Terror, the Surveillance Committees' activities were curtailed significantly. The new regime sought to restore legal norms and reduce the abuse of power that had characterized revolutionary justice. Nevertheless, the legacy of these committees underscored the intense measures revolutionaries were willing to employ to maintain the fledgling Republic amidst tumultuous times.
