The event commonly known as the "Reign of Terror" during the French Revolution occurred from September 1793 to July 1794 and was marked by extreme political purges and executions. Led by the Committee of Public Safety, particularly Maximilien Robespierre, the Reign of Terror aimed to defend the revolution from perceived enemies, both inside and outside France. Thousands of individuals, including political rivals, aristocrats, and common citizens, were executed by guillotine, fueling a climate of fear and suspicion. Ultimately, the Reign of Terror concluded with the fall of Robespierre, leading to a more moderate phase of the revolution and a backlash against radicalism.
