The end of the war brought a return to normalcy in terms of trade, and the renewing of ties of friendship and family. The end also brought out, in often poignant terms, the tragedy that such a conflict could have arisen between peoples so closely bound. But some things were different. Great Britain, preoccupied with its European and world concerns after the defeat of Napoleon, had learned a new respect for the United States. For its part, there would be no more talk of a “mere matter of marching” to conquer Canada in Washington’s corridors; the tough and dogged defense that had blunted American invasion efforts ensured that. And for the British North American colonies, the blurred lines that had marked the border with the United States had now become clear. The war ensured that there would be a different society to the north, following its own lights, and having fought for its existence -- as had its neighbour thirty years earlier. Out of that would grow mutual respect and an enduring friendship.
As for Virginia, which only ratified the Constitution at its convention on June 25, Hamilton writes in a letter to Madison that the collected edition of The Federalist had been sent to Virginia; Furtwangler presumes that it was to act as a "debater's handbook for the convention there," though he claims that this indirect influence would be a "dubious distinction."  Probably of greater importance to the Virginia debate, in any case, were George Washington's support for the proposed Constitution and the presence of Madison and Edmund Randolph , the governor, at the convention arguing for ratification.
