Explanation: On February 10, 1763, the Treaty of Paris brought the French and Indian War to a close, and all lands previously controlled by the French were now under British control. American Indians in the Ohio Country, Illinois Country, and Great Lakes region feared the loss of their French allies and the influx of colonists from east of the Appalachian Mountains settling on their land. To prevent the incursion of colonial settlers, Pontiac encouraged Ohio Country tribes to unite and to rise up against the British.
