The western theater of the American Revolutionary War (1775–1783) was the area of conflict west of the Appalachian Mountains, the region which became the Northwest Territory of the United States as well as what would become the states of Arkansas, Kentucky, Louisiana, Missouri, and Tennessee. The western war was fought between American Indians with their British allies in Detroit, and American settlers south and east of the Ohio River, and also the Spanish as allies of the latter.
