What was the name of the first republic established during the French Revolution?

The first republic established during the French Revolution was the French First Republic.

It was founded in September 1792, when the newly elected National Convention abolished the French monarchy. The change followed the insurrection of 10 August 1792, which suspended King Louis XVI, and the revolutionary victory over Prussian forces at Valmy on 20 September. The Convention formally declared France a republic on 21–22 September.

The First Republic lasted until 1804, but its government changed several times. The National Convention governed during the revolution’s most turbulent years, including the Reign of Terror. In 1795, the Directory took power under a new constitution, and in 1799 Napoleon Bonaparte’s coup created the Consulate.

The name “French First Republic” is retrospective: contemporaries generally called the state the French Republic. It is called “first” because France later established the Second Republic in 1848, followed by the Third Republic in 1870. Napoleon’s proclamation as Emperor in 1804 ended the First Republic and began the First French Empire.
