Eighteenth-century painted portrait of Maximilien de Robespierre wearing a brown striped coat, high collar, and white cravat, set against a plain background. — Maximilien Robespierre One of the leading figures of the French Revolution, Maximilien Robespierre.

The Reign of Terror (1793–1794) was primarily driven by the desperate need to preserve the French Revolution amidst existential threats. By the spring of 1793, France faced a dual crisis: hostile foreign powers surrounded its frontiers, while internal counterrevolutionary insurrections, most notably the civil war in the Vendée, threatened the government from within.123

In response to these pressures, the National Convention empowered the Committee of Public Safety, led by figures such as Maximilien Robespierre, to consolidate authority. On September 5, 1793, the government decreed that "terror is the order of the day," resolving to eliminate opposition to ensure the Revolution's survival. This centralized, dictatorial power was deemed necessary to enforce mass conscription, manage the economy through price controls, and suppress perceived enemies—including nobles, priests, and hoarders—who were viewed as obstacles to national unity.1423

Ultimately, while these harsh measures and the mobilization of a national army successfully repelled foreign invaders, they also destabilized the country and led to the execution of thousands, eventually contributing to the collapse of Robespierre’s regime.143
