The chapter discusses the transition of Britain's North American empire in the late 18th century, including the loosening of ties between Britain and its colonies, struggles over land with France and Native American groups, and the growing unrest in the colonies that eventually led to the American Revolution. As Britain tightened control over the colonies after the Seven Years' War, the colonies increasingly resisted British policies through protests and boycotts. This rising tensions came to a head at Lexington and Concord, marking the official start of the Revolutionary War.
