Convention and Terror, 1792–94, is where the French Revolution turns violent and radical. In Edexcel IGCSE History (4HI1) you must explain how the National Convention executed the king, how the Committee of Public Safety and Robespierre used terror to defend the Republic, and why tens of thousands died. Examiners love causation and judgement here: why did the Terror happen, and how far was it justified?

Key takeaways

• The National Convention met from September 1792, abolished the monarchy and declared the Republic.
• Louis XVI was executed by guillotine on 21 January 1793; Marie Antoinette followed in October 1793.
• The Committee of Public Safety (from April 1793), dominated by Maximilien Robespierre, ran France during the emergency.
• The Reign of Terror (1793–94) used the Law of Suspects and the Revolutionary Tribunal; tens of thousands were killed.
• The Convention was split between moderate Girondins and radical Jacobins (Montagnards).

Why did the Convention execute the king?

Direct answer: after the monarchy was abolished, the Convention put Louis XVI on trial for treason, found him guilty of conspiring against the Republic, and executed him on 21 January 1793. His death made the Republic irreversible — there could be no easy return to monarchy — and shocked the monarchies of Europe into war against France. Read the detail on the Convention and Terror subtopic page.

Girondins vs Jacobins: why the Convention split

The Convention was divided into factions. The Girondins were more moderate and favoured a less centralised republic; the Jacobins, or Montagnards, were radicals who wanted decisive action to save the revolution, backed by the Paris sans-culottes. Between them sat the uncommitted “Plain”. As war and internal revolt worsened in 1793, the Jacobins seized control and purged the Girondins, opening the way to the Terror.

Why did the Terror happen?

Direct answer: the Reign of Terror was the Jacobins’ response to an emergency — France faced foreign invasion (war with much of Europe), internal revolt (notably in the Vendée), and economic crisis. To defend the Republic, the Committee of Public Safety under Robespierre used extreme measures: the Law of Suspects (1793), the Revolutionary Tribunal, mass conscription (levée en masse, August 1793) and price controls. Thousands judged “enemies of the revolution” were guillotined.

The role of Robespierre

Maximilien Robespierre, leading member of the Committee of Public Safety, became the dominant figure of the Terror. He justified terror as the “virtue” needed to protect the Republic, and promoted the Cult of the Supreme Being. But as the external threat eased, the continuing executions made him feared even among fellow revolutionaries — setting up his downfall in July 1794.

Convention and Terror in exam wording

Command word / stem	What the question wants	1792–94 example
Describe two features of…	Two supported points	”Describe two features of the Reign of Terror.”
Explain why…	Linked causes	”Explain why the Committee of Public Safety was set up in 1793.”
How far do you agree…	Balanced judgement	“‘The Terror was necessary to save the Republic.’ How far do you agree?”

Worked exam-style stems

1. “Describe two features of the Reign of Terror.” Feature 1: the Law of Suspects allowed arrest of “enemies” + development (little evidence needed). Feature 2: the Revolutionary Tribunal sent thousands to the guillotine + development (executions rose sharply in 1793–94).
2. “Explain why the Terror happened.” Chain the causes: foreign war + internal revolt → sense of emergency → Committee of Public Safety and Law of Suspects → mass executions to defend the Republic. Reward: developed cause and effect.

Common mistakes students make

• Forgetting the date of Louis XVI’s execution (21 January 1793) — a key anchor.
• Confusing the Girondins (moderate) with the Jacobins/Montagnards (radical).
• Treating the Terror as random cruelty rather than a response to war and revolt.
• Assuming the Terror lasted for years — its most intense phase was 1793–94.
