The primary outcome of the Treaty of Paris in 1763 was the conclusion of the French and Indian War, significantly altering the territorial control in North America. France ceded most of its North American territories to Britain, including Canada and land east of the Mississippi River. This treaty marked the end of French colonial ambitions on the continent and solidified British dominance in North America. Additionally, it increased tensions between Britain and the American colonies due to the rising costs of British governance, setting the stage for the later revolutionary unrest and the quest for independence.
