The Coronation of Louis XVI in Reims, the last coronation before the French Revolution.

The coronation of Louis XVI, King of France and Navarre took place in Reims Cathedral on 11 June 1775, which fell on Trinity Sunday. Louis XVI had come to the throne the previous year in succession to his grandfather Louis XV who had reigned for 59 years. It was the first coronation since 1722 and only the second since 1654 due to the longevity of the two previous monarchs, Louis XIV and Louis XV.

Reims is the most populous city in the French department of Marne, and the 12th most populous city in France. The city lies 129 km (80 mi) northeast of Paris on the Vesle river, a tributary of the Aisne.

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.

June 11 is the 162nd day of the year in the Gregorian calendar; 203 days remain until the end of the year.
