The revolutionary figure known for leading the French Revolution is Maximilien Robespierre. A prominent member of the Committee of Public Safety, Robespierre played a significant role in the radical phase of the Revolution, advocating for democracy and the rights of the sans-culottes, the working-class revolutionaries. He is closely associated with the Reign of Terror, a period marked by political purges and executions of perceived enemies of the revolution, using the guillotine as a symbol of revolutionary justice. His influence grew until his fall from power in 1794, leading to his arrest and execution, marking the end of the radical phase of the revolution.
