The Peace of Paris of 1763 brought the first British empire to the summit of its power and glory, and set the problems of diplomacy and imperial organisation which in the next generation became the chief substance of English politics. In America the power of France was broken, but the problem of imperial defence remained, for as the Pontiac rebellion showed, Indian power could still be a menace, and perhaps a stalking-horse for renewed French ambitions. By the proclamation of 1763 the British government sought to keep white settlers out of the Indian hunting grounds where they had aroused great hostility, and in attempting to restrict expansion set themselves in opposition to some of the most powerful forces of American life. A standing army was also to be maintained, controlled from England but paid for by the colonists. To men of influence on both sides of the Atlantic the time also seemed ripe for a reorganisation of the constitutional machinery of the colonies, which had frequently obstructed the efficient conduct of the last war. Hitherto the British government had concentrated upon the control of the maritime and commercial links of empire, and under its system of imperial autarky the American colonies had flourished, rapidly increasing in population, extent and prosperity. To a very late date few Americans openly opposed imperial regulation of this sort, but they distinguished sharply between legislation which sought primarily to regulate trade, and that which sought primarily to raise revenue.
