The main outcome of the French and Indian War (1754-1763) was the substantial territorial gains for Britain in North America, including Canada and land east of the Mississippi River. However, the war deeply strained British finances, leading to increased taxation of the American colonies, which fueled resentment. The war also resulted in the weakening of French influence in North America and heightened tensions with Native American tribes, as British expansion into their territories escalated conflicts. Ultimately, the war set the stage for the American Revolution, as colonial dissatisfaction grew over British policies and governance.
