The legacy of the Treaty of Paris in 1763 was significant, as it ended the Seven Years' War and marked the beginning of British hegemony in North America. The treaty granted Britain extensive territorial gains, including Canada and Florida, while France ceded its territories east of the Mississippi River. This shift altered the balance of colonial power and deepened tensions between Britain and its American colonies due to increased taxes and regulations to offset war debts. Ultimately, it set the stage for growing discontent that fueled the American Revolution two decades later.
