Pontiac's Rebellion (1763–1766) was an Indian uprising led by Ottawa chief Pontiac against British settlers in the Ohio Valley and Great Lakes after the French and Indian War. Allied with other tribes and inspired by a Delaware prophet, Pontiac attacked British forts and settlers, often using deception. While many forts fell, Detroit and Fort Pitt held out. In western Virginia, Shawnee warriors killed dozens of settlers. The rebellion ended in 1766 when Pontiac, unable to rally broader tribal support, made peace. He was later killed by an Indian in Illinois.
