The French and Indian War was a conflict fought in North America from 1754 to 1763 between Great Britain and France, along with their respective Native American allies. It is considered the North American theater of the larger global conflict known as the Seven Years' War. The war involved battles over territorial claims, especially in the Ohio River Valley, and the control of trade routes and colonies. The French allied with various Native American tribes, while the British were supported mainly by the Iroquois Confederacy. The war featured both traditional European military tactics and guerrilla- style warfare influenced by Native American combat methods. Ultimately, Britain won the war, gaining significant territorial control in North America and ending France's colonial presence east of the Mississippi River. This war set the stage for future conflicts including tensions leading to the American Revolution.
