King William's War (also known as the Second Indian War, Father Baudoin's War, Castin's War, or the First Intercolonial War in French) was the North American theater of the Nine Years' War (1688–1697), also known as the War of the Grand Alliance or the War of the League of Augsburg. It was the first of six colonial wars (see the four French and Indian Wars, Father Rale's War and Father Le Loutre's War) fought between New France and New England along with their respective Native allies before France ceded its remaining mainland territories in North America east of the Mississippi River in 1763.
