The Treaty of Paris in 1763 marked the end of the Seven Years' War (also known as the French and Indian War in North America) and significantly reshaped the geopolitical landscape. The treaty resulted in France ceding Canada and all its territories east of the Mississippi River to Britain, while Spain gave up Florida but received New Orleans and the territory west of the Mississippi. This outcome solidified British dominance in North America and allowed for westward expansion. It also fueled subsequent tensions between Britain and its American colonies, contributing to the American Revolution a decade later.
