The Treaty of Paris, signed in 1763, ended the French and Indian War. It also gave large tracts of Algonquian Indian land to Britain. This angered the great chief Pontiac. Pontiac, leader of a league of 18 Algonquian-speaking tribes, began a campaign against the British forts in what was then the Northwest, the territory between the Ohio and Missippi rivers. In a little over a month, the Algonquian had overrun nine British forts. The well-organized Indian offensive slowed in the summer of 1763, when Pontiac failed to capture the major British post at Detroit. In 1765, the British struck back. After a truce the next year, Pontiac accepted the "peace belt" from the British and the conflict was over. The failure of Pontiac's rebellion marked the end of the Algonquian Confederacy. The engraving above shows Pontiac's warriors attacking a British fort.
