American Indian tribes formerly allied with the French were dissatisfied with the British occupation, which brought new territorial policies. Whereas the French cultivated alliances among the Indians, the British postwar approach was to treat the tribes as conquered peoples. In 1763, tribes united in Pontiac's Rebellion to try to drive the British from the area. American Indians captured Fort Michilimackinac, at present-day Mackinaw City, then the principal fort of the British in the Michilimackinac region, as well as others and killed hundreds of British. In 1764, they began negotiations with the British which resulted in temporary peace and changes in objectionable British policies.
