Answer:
The American Indian group that was allied with the British as the French and Indian War began was the Iroquois Confederacy.
Step-by-step explanation:
During the French and Indian War between the French and the British in North America, the Iroquois Confederacy joined the British against the French and their allied Algonquin peoples, both traditional enemies of the Iroquois. In practice, few Iroquois joined the fighting, most of them during the Battle of Lake George, when a group of Frenchmen ambushed a British-Iroquois column. As a compensation for the participation in this war, the British government issued a Royal Proclamation in 1763, which imposed restrictions on white settling west of the Appalachians.
