With France removed from North America, the vast interior of the continent lay open for the Americans to colonize. But The English government decided otherwise. To induce a controlled population movement, they issued a Royal Proclamation that prohibited settlement west of the line drawn along the crest of the Alleghenny mountains and to enforce that meassure they authorized a permanent army of 10,000 regulars (paid for by taxes gathered from the colonies; most importantly the "Sugar Act" and the "Stamp Act"). This infuriated the Americans who, after having been held back by the French, now saw themselves stopped by the British in their surge west.
