King William's War

King William's War (1688–97, also known as the Second Indian War, Father Baudoin's War, or Castin's War) was the North American theater of the Nine Years' War (1688–97, 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 Britain eventually defeated France in North America in 1763.

For King William's War, neither England nor France thought of weakening their position in Europe to support the war effort in North America. New France and the Wabanaki Confederacy were able to thwart New England expansion into Acadia, whose border New France defined as the Kennebec River in southern Maine. According to the terms of the Treaty of Ryswick, the boundaries and outposts of New France, New England, and New York remained substantially unchanged.
