In the end Louis's grandson was recognized as king of Spain, but he was obliged to agree to the forfeiture of succession rights in France, the Spanish Habsburgs' other European territories were largely ceded to Austria, and France was nearly bankrupted by the cost of the struggle. Louis died on 1 September 1715 ending his seventy-two-year reign, the longest in European history. The reign of Louis XIV was so long that he outlived both his son and eldest grandson. He was succeeded by his great-grandson Louis XV. Louis XV was born on 15 February 1710 and was thus aged only five at his ascension, the third Louis in a row to become king of France before the age of thirteen (Louis XIII became king at 9, Louis XIV at almost 5 and himself at 5). Initially, the regency was held by Philippe, Duke of Orléans, Louis XIV's nephew, as nearest adult male to the throne. This Régence was seen as a period of greater individual expression, manifested in secular, artistic, literary and colonial activity, in contrast to the austere latter years of Louis XIV's reign. Following Orléans' death in 1723, the Duke of Bourbon, representative of the Bourbon-Condé cadet line, became prime minister. It was expected that Louis would marry his cousin, the daughter of King Philip V of Spain, but this engagement was broken by the duke in 1725 so that Louis could marry Maria Leszczynska, the daughter of Stanislas, former king of Poland. Bourbon's motive appears to have been a desire to produce an heir as soon as possible so as to reduce the chances of a succession dispute between Philip V and the Duke of Orléans in the event of the sickly king's death. Maria was already an adult woman at the time of the marriage, while the infanta was still a young girl. Nevertheless, Bourbon's action brought a very negative response from Spain, and for his incompetence Bourbon was soon replaced by Cardinal André-Hercule de Fleury, the young king's tutor, in 1726. Fleury was a peace-loving man who intended to keep France out of war, but circumstances presented themselves that made this impossible. The first cause of these wars came in 1733 when Augustus II, the elector of Saxony and king of Poland died. With French support, Stanislas was again elected king. This brought France into conflict with Russia and Austria who supported Augustus III, Elector
