Louis VI (1 December 1081 – 1 August 1137), called the Fat , was King of the Franks from 1108 until his death (1137). Chronicles called him "roi de Saint-Denis". Louis was the first member of the House of Capet to make a lasting contribution to the centralizing institutions of royal power, He spent almost all of his twenty-nine-year reign fighting either the "robber barons" who plagued Paris or the Norman kings of England for their continental possession of Normandy. Nonetheless, Louis VI managed to reinforce his power considerably and became one of the first strong kings of France since the division of the Carolingian Empire in 843.

Louis XVI (; 23 August 1754 – 21 January 1793), born Louis-Auguste, also known as Louis Capet was King of France from 1774 until his deposition in 1792, although his formal title after 1791 was King of the French. He was guillotined on January 21, 1793. His father, Louis, Dauphin of France, was the son and heir apparent of Louis XV of France, but his father died in 1765, and Louis succeeded his grandfather as king in 1774.
