MAP 5.2 British Conflicts with Indians, 1758–1763, and the Proclamation Line The entrance of British troops into former French territory in the Ohio River valley following the French and Indian War fueled conflicts with Indian nations. Colonists in Pennsylvania and the Carolinas also battled with Indians, including tribes who were allies or remained neutral during the war. Parliament established the Proclamation Line to limit westward expansion and thereby diminish such hostilities.
