Why did Ottawa Chief Pontiac lead a rebellion in 1763?

Pontiac's War, also known as Pontiac's Conspiracy or Pontiac's Rebellion, was launched in 1763 by a loose confederation of American Indian tribes, primarily from the Great Lakes region, the Illinois Country, and Ohio Country who were dissatisfied with British policies in the Great Lakes region following the French and Indian War (1754–1763). Warriors from numerous tribes joined the uprising in an effort to drive British soldiers and settlers out of the region. The war is named after Odawa leader Pontiac, the most prominent of many Indian leaders in the conflict.
