The Treaty of Paris (1763) ended the Seven Years' War and significantly redefined colonial territories between Britain, France, and Spain. As a result of the treaty, France ceded Canada and all its territories east of the Mississippi River to Britain, while Spain ceded Florida to Britain but received Louisiana from France in return. This reallocation marked a crucial shift in colonial power dynamics, establishing Britain as the dominant imperial force in North America. The treaty also laid the groundwork for future tensions between the British government and its American colonies, contributing to the conditions that eventually led to the American Revolution.
