Which conflict was primarily fought over territorial expansion between Britain and France in North America?

The conflict primarily fought over territorial expansion between Britain and France in North America is clearly the French and Indian War. This war, which took place from 1754 to 1763, was a crucial part of the global conflict known as the Seven Years' War. The primary contention during this war revolved around the control of North American territories, particularly the Ohio River Valley, which both British and French colonial powers sought to expand into.

The French and Indian War is characterized by its competition for land and resources, as both sides aimed to secure and grow their territories in the face of each other’s colonial ambitions. With Native American tribes often aligned with either the French or the British, the scope of the conflict also involved significant alliances that further complicated the territorial disputes.

In contrast, the other conflicts listed had different focal points. The War of 1812 was more about national sovereignty and maritime rights against British impressment of American sailors, while the American Revolutionary War involved American colonies seeking independence from British rule rather than a direct territorial dispute with France. The Mexican-American War, taking place later in the 19th century, was centered on the U.S. expansion into present-day Mexico and was not directly related to British and French territorial rivalry in North America.
