The Champ de Mars (located in Paris, near the Eiffel Tower) was a significant site during the French Revolution. It became a focal point for many pivotal events, including demonstrations and gatherings that influenced the course of the Revolution. On 17 July 1791, it was the location of the infamous Champ de Mars Massacre. This incident occurred after the National Constituent Assembly issued a decree that King Louis XVI would remain king under a constitutional monarchy, which many Parisians opposed. A large crowd gathered on the Champ de Mars to sign a petition demanding the establishment of a republic. The protestors, led by figures such as Georges Danton and Camille Desmoulins, aimed to pressure the Assembly to take a more radical course. However, the assembly, along with the Paris Commune, was concerned about the growing unrest and potential violence. In response, the National Guard (led by General Lafayette) was dispatched to maintain order. Tensions escalated when two supposed spies were found among the protesters and subsequently lynched. Lafayette's troops, facing an increasingly aggressive crowd, attempted first to disperse the assembly with warnings and blank shots. When the crowd refused to disperse, live ammunition was used, resulting in the deaths of dozens of demonstrators. The massacre marked a significant escalation in the revolution’s internal conflicts and deepened the divide between moderate revolutionaries and their more radical counterparts. Following the massacre, the Champ de Mars continued to be a central location for revolutionary events. It witnessed various civic gatherings, celebrations, and significant revolutionary festivals. For instance, the Festival of the Supreme Being (organised by Maximilien Robespierre) was held there on 8 June 1794. The site persisted as a symbol of both revolutionary fervor and the violent struggles that characterised the period.
