The three groups living in America that did not fight the British were Loyalists, Native Americans, African Americans
Explanation:
Loyalists didn't fight the British since this sector of the population was formed with colonists who kept their loyalty to the British Crown during the American Revolutionary War.
Native Americans, played an important role in the American Independence but to defend Canada, and as a way to rescue British support.
African Americans were sent to war by their owners with the offer of liberty when they come back, so they fought with Patriot forces.
