At the end of the War of the League of Augsburg (1689-1697), France and the Duchy of Savoy sealed their reconciliation with a new dynastic union: the marriage of the Duke of Burgundy to Marie-Adélaïde of Savoy. The only one of their children to survive the measles epidemic that killed the duke and duchess too was the future Louis XV.
A ball was held in the Hall of Mirrors to celebrate the royal wedding in december 1697.
