Jacobins

The Society of the Friends of the Constitution (), renamed the Society of the Jacobins, Friends of Freedom and Equality () after 1792 and commonly known as the Jacobin Club () or simply the Jacobins (; ), was the most influential political club during the French Revolution of 1789. The period of its political ascendancy includes the Reign of Terror, during which well over 10,000 people were put on trial and executed in France, many for "political crimes".

Initially founded in 1789 by anti-royalist deputies from Brittany, the club grew into a nationwide republican movement with a membership estimated at a half million or more. The Jacobin Club was heterogeneous and included both prominent parliamentary factions of the early 1790s: The Mountain and the Girondins. In 1792–93, the Girondins were more prominent in leading France when they declared war on Austria and on Prussia, overthrew King Louis XVI, and set up the French First Republic. In May 1793, the leaders of the Mountain faction, led by Maximilien Robespierre, succeeded in sidelining the Girondin faction and controlled the government until July 1794. Their time in government featured high levels of political violence, and for this reason the period of the Jacobin/Mountain government is identified as the Reign of Terror. In October 1793, 21 prominent Girondins were guillotined. The Mountain-dominated government executed 17,000 opponents nationwide as a way to suppress the Vendée insurrection and the Federalist revolts, and to deter recurrences. In July 1794, the National Convention pushed the administration of Robespierre and his allies out of power and had Robespierre and 21 associates executed. In November 1794, the Jacobin Club closed.
