Who was great britain opponent during the french and indian war

France.

The French and Indian War was between reat Britain and France and their Indian allies.

Also known as the Seven Years’ War, this New World conflict marked another chapter in the long imperial struggle between Britain and France. When France’s expansion into the Ohio River valley brought repeated conflict with the claims of the British colonies, a series of battles led to the official British declaration of war in 1756. Boosted by the financing of future Prime Minister William Pitt, the British turned the tide with victories at Louisbourg, Fort Frontenac and the French-Canadian stronghold of Quebec. At the 1763 peace conference, the British received the territories of Canada from France and Florida from Spain, opening the Mississippi Valley to westward expansion.
