What treaty ended the French and Indian War by granting Britain significant territorial gains?

The Treaty of Paris 1763 is the correct answer because it formally concluded the French and Indian War, which took place between 1754 and 1763, primarily on North American soil. This treaty was signed between Great Britain, France, and Spain, establishing significant changes in territorial claims in North America. As a result of the treaty, Britain gained control of Canada and all French territory east of the Mississippi River, significantly expanding its colonial holdings. The treaty diminished French colonial presence in North America while enhancing British influence, laying the groundwork for future tensions with the American colonies and other nations due to the new territorial boundaries.

Other options do not pertain to the conclusion of the French and Indian War. The Treaty of Utrecht was signed in 1713 and resolved earlier European conflicts, while the Treaty of Ghent concluded the War of 1812 between the United States and Britain. The Paris Peace Accord is related to the Vietnam War discussions held in the early 1970s. Thus, the Treaty of Paris 1763 directly relates to the territorial changes following the French and Indian War.
