Louis XVI: Execution by guillotine — French Revolution The execution of Louis XVI in 1793.

Louis XVI was executed on January 21, 1793, primarily because he was found guilty of treason by the National Convention.12

Following the abolition of the monarchy in September 1792, the former king—referred to as "Citizen Capet"—faced trial for his role in counterrevolutionary activities. Evidence discovered in a secret cupboard at the Tuileries Palace in November 1792 confirmed his secret dealings with foreign powers and his involvement in intrigues against the Revolution.32

Ultimately, Louis XVI was unwilling to cede his royal power to the revolutionary government, and his attempts to escape the capital and his reliance on foreign intervention to restore his authority led to his condemnation. The execution served as a definitive act for the National Convention, signaling that there could be no return to the monarchy and establishing the deputies as regicides committed to the new Republic.132
