French Revolution: The National Convention abolishes the monarchy.

The French Revolution was a period of political and societal change in France which began with the Estates General of 1789 and ended with the Coup of 18 Brumaire on 9 November 1799. Many of the revolution's ideas are considered fundamental principles of liberal democracy, and its values remain central to modern French political discourse. It was caused by a combination of social, political, and economic factors which the existing regime proved unable to manage.

The National Convention was the constituent assembly of the Kingdom of France for one day and the French First Republic for its first three years during the French Revolution, following the two-year National Constituent Assembly and the one-year Legislative Assembly. Created after the insurrection of 10 August 1792, it was the first French government organized as a republic, abandoning the monarchy altogether. The Convention sat as a single-chamber assembly from 20 September 1792 to 26 October 1795.

During the French Revolution, the proclamation of the abolition of the monarchy was a proclamation by the National Convention of France announcing that it had abolished the French monarchy on 21 September 1792, giving birth to the French First Republic.
