The Treaty of Paris 1763 resolved the crisis stemming from the Seven Years' War, also known as the French and Indian War in North America. This treaty marked the end of the conflict between Britain and France, significantly altering the balance of power in North America and Europe. Under its terms, France ceded Canada and all its territories east of the Mississippi River to Britain, while Spain, an ally of France, ceded Florida to Britain in exchange for the return of Havana, Cuba. This treaty established Britain as the dominant colonial power in North America, leading to increased tensions with Native American tribes and ultimately contributing to the American Revolution.
