French Revolution: Storming of the Tuileries Palace: Louis XVI is arrested and taken into custody as his Swiss Guards are massacred by the Parisian mob.

The French Revolution was a period of political and societal change in France which began with the Estates General of 1789 and ended with the Coup of 18 Brumaire on 9 November 1799. Many of the revolution's ideas are considered fundamental principles of liberal democracy, and its values remain central to modern French political discourse. It was caused by a combination of social, political, and economic factors which the existing regime proved unable to manage.

The insurrection of 10 August 1792 was a defining event of the French Revolution, when armed revolutionaries in Paris, increasingly in conflict with the French monarchy, stormed the Tuileries Palace. The conflict led France to abolish the monarchy and establish a republic.

Louis XVI was the last king of France before the fall of the monarchy during the French Revolution. The son of Louis, Dauphin of France, and Maria Josepha of Saxony, Louis became the new Dauphin when his father died in 1765. In 1770, he married Marie Antoinette. He became King of France and Navarre on his grandfather's death on 10 May 1774, and reigned until the abolition of the monarchy on 21 September 1792. From 1791 onwards, he used the style of king of the French.

The Pontifical Swiss Guard, also known as the Papal Swiss Guard or simply Swiss Guard, is an armed forces, guard of honour, and protective security unit, maintained by the Holy See to protect the Pope and the Apostolic Palace within the territory of the Vatican City State. Established in 1506 under Pope Julius II, it is among the oldest military units in continuous operation and is sometimes called "the world's smallest army".
