Louis XV of France was born on February 15, 1710, in the Palace of Versailles. He became king at the age of five after his great-grandfather, Louis XIV, died in 1715. His reign was marked by political unrest, economic problems, and social unrest. Louis XV was heavily influenced by his mistresses, who exerted great power over him and his court. Under the reign of Louis XV, France lost its territory in North America during the Seven Years' War. The country also experienced a major debt crisis due to military spending and the cost of maintaining the lavish lifestyle of the court. Louis XV died on May 10, 1774, at Versailles after having ruled for 59 years. He was succeeded by his grandson, Louis XVI. Despite the problems that occurred during his reign, Louis XV was a patron of the arts and culture, and he also supported education and science.
