British troops then occupied the various forts in the Ohio Country and Great Lakes region previously held by the French. Even before the war officially ended with the Treaty of Paris (1763), the British Crown began to implement changes in order to administer its vastly expanded North American territory. The politics of the French and the English was different, though. The French had made alliaces with certain Native American tribes, and traded with them. After the war, these Native American tribes were conquered people. Before long, Native Americans who had been allies of the defeated French were more and more dissatisfied with the British occupation and the new policies imposed by the victors.
