1792–1794: Republic and Terror

The years 1792 to 1794 represent the Revolution at its most radical. France abolished the monarchy, declared a republic, executed the king, fought a continent-wide war, and subjected itself to a revolutionary dictatorship that consumed many of its own architects.

War and the Fall of the Monarchy

On April 20, 1792, France declared war on Austria, beginning a conflict that would eventually engulf most of Europe and last, with interruptions, until 1815. The war was supported by different factions for different reasons: the Girondins hoped it would expose the king’s treasonous sympathies; the king hoped French defeats would lead to foreign intervention restoring his power.

Early French defeats seemed to confirm the worst fears. On July 25, the Duke of Brunswick, commanding the Austrian and Prussian armies, issued a manifesto threatening to destroy Paris if the royal family were harmed. Far from intimidating the revolutionaries, the Brunswick Manifesto enraged them.

On August 10, 1792, a crowd of sans-culottes (radical working-class Parisians) and fédérés (provincial National Guard volunteers) stormed the Tuileries Palace. The Swiss Guards defending the palace were massacred — approximately 600 of the 900 guards were killed. Louis XVI and his family took refuge with the Legislative Assembly, which voted to suspend the monarchy and call elections for a new body, the National Convention, to draft a republican constitution.

The September Massacres

In early September 1792, with Prussian armies advancing on Paris, panic gripped the city. Rumors spread that imprisoned counter-revolutionaries and common criminals would break out and attack from within. Between September 2 and 7, mobs invaded Paris prisons and massacred between 1,100 and 1,400 prisoners — aristocrats, priests, common criminals, and prostitutes alike. Impromptu “tribunals” offered a thin pretense of legality before sending victims to be hacked to death.

The September Massacres horrified moderate opinion in France and across Europe. They demonstrated the lethal power of revolutionary crowd violence and the inability — or unwillingness — of authorities to control it.

The Republic and the Trial of the King

The National Convention, elected by universal male suffrage, met on September 20, 1792 — the same day French forces won their first significant victory at the Battle of Valmy, stopping the Prussian advance. The next day, September 21, the Convention abolished the monarchy and declared France a republic.

Louis XVI was put on trial before the Convention in December 1792, charged with treason and conspiracy with foreign powers. His guilt was near-unanimously affirmed, but the vote on his sentence was agonizingly close: 361 deputies voted for immediate execution, 360 for alternatives ranging from imprisonment to conditional death. Louis was guillotined on January 21, 1793, in the Place de la Révolution (now Place de la Concorde).

The king’s execution shocked Europe and led to the formation of the First Coalition — an alliance of Britain, the Dutch Republic, Spain, Portugal, and several Italian and German states — against France. France now faced war on virtually every border.

The Reign of Terror (September 1793 – July 1794)

By mid-1793, the Republic was besieged on all sides: foreign armies invaded from the north, east, and south; royalist rebels controlled much of western France (the Vendée uprising) and parts of the south; and economic crisis threatened the cities with famine.

In response, the Convention centralized power in the Committee of Public Safety, a twelve-member executive body dominated by Maximilien Robespierre, Louis Antoine de Saint-Just, and Georges Couthon. The Committee wielded near-absolute authority, directing the war effort, managing the economy, and crushing dissent.

The Law of Suspects (September 17, 1793) authorized the arrest of anyone deemed hostile to the Revolution. The Revolutionary Tribunal in Paris and similar bodies throughout France conducted swift trials with limited rights of defense. Execution by guillotine became routine.

Key events and victims of the Terror included:

• Marie Antoinette: Tried and executed on October 16, 1793, after a trial that included fabricated charges of incest.
• The Girondins: Twenty-one leading Girondin deputies were guillotined on October 31, 1793, victims of their political rivalry with the Montagnards (the Jacobin-aligned radical faction).
• Danton and the Indulgents: Georges Danton, once a pillar of the Revolution, called for moderation and an end to the Terror. He was arrested, tried, and executed on April 5, 1794. His famous last words to the executioner: “Show my head to the people; it is worth seeing.”
• Hébertists: Jacques Hébert and his radical followers, who pushed for extreme de-Christianization, were executed on March 24, 1794 — just days before Danton.

The Vendée and Civil War

The Vendée uprising in western France was the most serious internal threat to the Republic. Beginning in March 1793, it was triggered by the Convention’s decree of mass conscription (levée en masse) and fueled by attachment to the Catholic Church and the monarchy. The Vendéan rebels — peasants, artisans, and local nobles — formed the Catholic and Royal Army and won several early battles against republican forces.

The Republic’s response was brutal. General Louis Marie Turreau’s “infernal columns” swept through the Vendée in early 1794, carrying out systematic destruction of villages and mass killings of civilians. Modern historians estimate that between 170,000 and 300,000 people died in the Vendée conflict — some historians have characterized the repression as genocide, though this characterization remains debated.

The Republic of Virtue

Robespierre and Saint-Just envisioned the Terror not merely as a wartime emergency but as a tool for creating a virtuous republic. They promoted the Cult of the Supreme Being — a deistic civic religion intended to replace Catholicism — and the Republican Calendar, which replaced the Gregorian calendar with a rational system of ten-day weeks and months named for natural phenomena.

Revolutionary culture permeated daily life: citizens addressed each other as “citoyen” and “citoyenne,” the informal “tu” replaced the formal “vous,” and aristocratic styles of dress were abandoned in favor of the sans-culotte costume of trousers, carmagnole jacket, and red liberty cap.

The Fall of Robespierre (9 Thermidor / July 27, 1794)

By the summer of 1794, the Terror had consumed so many factions that remaining Convention deputies feared they would be next. On 9 Thermidor Year II (July 27, 1794), a coalition of deputies turned against Robespierre. He was arrested, and after a failed rescue attempt, was guillotined the next day along with Saint-Just, Couthon, and nineteen allies.

The Thermidorian Reaction that followed dismantled the machinery of Terror: the Revolutionary Tribunal was reformed, the Committee of Public Safety was stripped of its powers, and thousands of political prisoners were released. The surviving Girondins were rehabilitated. The radical phase of the Revolution was over.
