The Seven Years' War, also known as the French and Indian War in North America, took place from 1756 until 1763. This global conflict pitted Britain against France for control over North America, specifically the regions encompassing the Ohio River Valley and what would become the eastern portion of the United States and Canada. Following the Battle of Quebec in 1760, a significant turning point, Britain eventually emerged victorious The war began over rival claims in the region, including concerns of Virginia planters over tobacco prices and the land-grant given to the Ohio Company. The French, aiming to protect their claims, built Fort Duquesne in present-day Pittsburgh, Pennsylvania. The ensuing conflict drew in various Native American tribes that allied with either the British or the French, further amplifying the scale and impact of the war.In conclusion, the Treaty of Paris (1763) ended the war, awarding Britain with vast territories and firmly establishing it as the dominant European power in eastern North America.
