Final answer:
Great Britain won the French and Indian War, and the Treaty of Paris in 1763 marked the end of New France, granting Britain vast territories in North America.
Step-by-step explanation:
The conclusion of the French and Indian War, also known in Europe as the Seven Years' War, saw Great Britain emerge victorious over France and its allies. This final imperial conflict, which stretched from 1754 to 1763, was primarily fought over territorial disputes along the frontier, most notably in the region surrounding the Ohio River Valley. Great Britain's triumph was solidified with the signing of the Treaty of Paris in 1763, which led to a monumental transfer of territories, with Great Britain gaining almost all the French territory in North America. This marked the end of New France and solidified British dominance in eastern North America, while also resulting in the acquisition of other French outposts around the world.
