The French and Indian War was fought from 1754 to 1763 between Great Britain and France over control of territory in North America. Great Britain allied with American colonists and the Iroquois nation, while France allied with Native American groups like the Huron and Algonquin. France controlled forts and settlements in Canada and along the Ohio Valley, blocking British expansion, while Britain had more settlers along the coast. The tide turned when William Pitt became British prime minister in 1757 and increased funding and troop levels, capturing Montreal in 1760. The Treaty of Paris in 1763 ended the war, ceding French North American lands to Britain.
