On 10 August 1792, during the French Revolution, revolutionary Fédéré militias — with the backing of a new municipal government of Paris that came to be known as the "insurrectionary" Paris Commune and ultimately supported by the National Guard — besieged the Tuileries palace. King Louis XVI and the royal family took shelter with the Legislative Assembly. This proved to be the effective end of the French Bourbon Monarchy (until it was restored in 1814, although the monarchical system of an empire had been introduced ten years earlier). The formal end of the monarchy occurred six weeks later, as one of the first acts of business of the new Convention.
