Indiana give up: they captured Fort Ouiatenon and Fort Miami during Pontiac's Rebellion. The British royal proclamation of 1763 designated the land west of the Appalachians for Native American use, and excluded British colonists from the area, which the Crown called "Indian Territory". In 1775, the American Revolutionary War began as the colonists sought self-government and independence from the British. The majority of the fighting took place near the East Coast, but the Patriot military officer George Rogers Clark called for an army to help fight the British in the west. Clark's army won significant battles and took over Vincennes and
Illinois campaign the region. When the American Revolutionary War began, in 1775, the Ohio River marked the border between the Illinois Country and Kentucky, an area recently settled by American colonists. The British had originally sought to keep American Indians out of the war, but in 1777 Lieutenant Governor Hamilton received instructions to recruit and arm Indian war parties to raid the Kentucky settlements, opening a western front in the war with the rebel colonists. "From 1777 on," wrote historian Bernard Sheehan, "the line of western settlements was under almost constant assault by white-led [Indian] raiding parties that had originated at Detroit."
