The significance of the French Reign of Terror (1793-1794) lies in its radical approach to political and social change during the French Revolution. Under the leadership of Robespierre and the Committee of Public Safety, the Reign of Terror sought to eliminate perceived enemies of the revolution, resulting in mass executions, including that of King Louis XVI and thousands of others. This period highlighted the extremes to which revolutionary ideals could lead, as it aimed to protect the republic but ultimately fostered fear and repression. The Reign of Terror significantly shaped the future of France and influenced revolutionary movements worldwide.
