The Reign of Terror was started on 5 September, 1793. The violence happened more and more often in June and July of 1794, a period called "la Grande Terreur" (The Great Terror). On 17 July 1794, sixteen nuns attracted much attention by singing a religious song as they were being executed for treason. The Terror ended ten days later, when several important leaders of the Reign of Terror were executed, including Saint-Just and Robespierre. The Terror took the lives of between 18,500 to 40,000 people.
