Who was the longest-reigning French monarch?

Louis XIV was King of France from 14 May 1643 until his death in 1715. He is a symbol of the Age of Absolutism in Europe for styling himself as "The Sun King" and "Louis the Great", which portrayed him as supreme leader. He presided over a great expansion of the French colonial empire and a patronage of arts in his court at the Palace of Versailles that defined the Baroque style of French architecture. His reign of 72 years and 110 days remains the longest of any sovereign monarch in history.
