Indians in western New York and Ohio also faced encroachment onto their lands. With the French threat removed, the British reduced the price paid for furs, allowed settlers to take Indian land without payments, and built forts in violation of treaties with local tribes. In the spring of 1763, an Ottawa chief named Pontiac led an alliance of Delaware, Seneca, Shawnee, and other western Indians in rebellion. Pontiac's alliance attacked forts in Indiana, Michigan, Pennsylvania, and Wisconsin that Britain had taken over from the French, destroying all but three. Pontiac's forces then moved eastward, attacking settlements in western Pennsylvania, Maryland, and Virginia, killing more than 2,000 colonists. Without assistance from the French, however, Pontiac's rebellion petered out by the year's end.
