The French and Indian War in North America, fought from 1754 to 1763, was primarily caused by territorial disputes between the British and French colonial empires over the Ohio River Valley and the fur trade. Both nations sought to expand their territories and influence in North America, leading to skirmishes and clashes over land claims. Native American tribes often allied with either side. The war culminated in British victory, resulting in significant territorial gains for Britain. However, the financial burden of the war ultimately led to increased taxation of the American colonies, sowing the seeds for colonial discontent and the American Revolution.
