Pontiac or Obwandiyag, was the Ottawa tribe leader who became famous for his role in Pontiac's Rebellion, an American Indian struggle against the British military occupation of the Great Lakes region following the British and Iroquois victory in the French and Indian War. Historians disagree about Pontiac's importance in the war that bears his name. Nineteenth century accounts portrayed him as the mastermind and leader of the revolt, while some subsequent interpretations have depicted him as a local leader with limited overall influence.The war began in May 1763 when Pontiac and 300 followers attempted to take Fort Detroit by surprise. His plan foiled, Pontiac laid siege to the fort, and was eventually joined by more than 900 warriors from a half-dozen tribes. Meanwhile, messengers spread the word of Pontiac's actions, and the war expanded far beyond Detroit. In July 1763, Pontiac defeated a British detachment at the Battle of Bloody Run, but he was unable to capture the fort.
