The British Empire and the United States spoke the same language. Their homelands, i.e the places where they make up the majority of residents, are the same: the British Empire with its American colonies then, and the United States and its "special relationship" with the U.K. and other Five Eyes nowadays. The leaders of the American Revolution were leading British Imperialists immediately before, e.g. George Washington led the 1760's campaign against the French in the Mississippi valley.
