The laws against theft were severe, and capital punishments unsparingly inflicted. Yet they had little effect in repressing acts of violence, to which a rude and licentious state of manners, and very imperfect dispositions for preserving the public peace, naturally gave rise. These were frequently perpetrated or instigated by men of superior wealth and power, above the control of the mere officers of justice. Meanwhile the kingdom was increasing in opulence, the English merchants possessed a large share of the trade of the north; and a woollen manufacture, established in different parts of the kingdom, had not only enabled the legislature to restrain the import of cloths, but begun to supply foreign nations. The population may probably be reckoned, without any material error, at about three millions, but by no means distributed in the same proportions as at present; the northern counties, especially Lancashire and Cumberland, being very ill peopled, and the inhabitants of London and Westminster not exceeding sixty or seventy thousand.[7] Such was the political condition of England, when Henry Tudor, the only living representative of the house of Lancaster, though incapable, by reason of the illegitimacy of the ancestor who connected him with it, of asserting a just right of inheritance, became master of the throne by the defeat and death of his competitor at Bosworth, and by the general submission of the kingdom. He assumed the royal title immediately after his victory, and summoned a parliament to recognise or sanction his possession. The circumstances were by no means such as to offer an auspicious presage for the future. A subdued party had risen from the ground, incensed by proscription and elated by success; the late battle had in effect been a contest between one usurper and another; and England had little better prospect than a renewal of that desperate and interminable contention, which the pretences of hereditary right have so often entailed upon nations.
