Louis XV, known as Louis the Beloved, was King of France from 1 September 1715 until his death in 1774. He succeeded his great-grandfather Louis XIV at the age of five. Until he reached maturity in 1723, the kingdom was ruled by his grand-uncle Philippe II, Duke of Orléans, as Regent of France. Cardinal Fleury was chief minister from 1726 until his death in 1743, at which time the king took sole control of the kingdom.
