Those wars are perhaps the most puzzling episode in English history. The action of an organized government is comparatively easy to follow, but it is impossible to analyze the politics of anarchy. The Yorkist claim to the throne was not the cause of the war; it was, like Edward III's claim to the throne of France, merely a matter of tactics, and was only played as a trump card. No political, constitutional, or religious principle was at stake; and the more peaceable, organized parts of the community took little share in the struggle. No great battle was fought south of the Thames, and no town stood a siege. It looks as though the great military and feudal specialists, whose power lay principally on the Borders, were engaged in a final internecine struggle for the control of England, in somewhat the same way as the Ostmark or East Border of the Empire became Austria, and the Nordmark or North Border became Prussia, and in turn dominated Germany. Certainly the defeat of these forces was a victory for southern and eastern England, and for the commercial and maritime interests on which its growing wealth and prosperity hung; and the most important point in the wars was not the triumph of Edward IV over the Lancastrians in 1461, but his triumph over Warwick, the kingmaker, ten years later. The New Monarchy has been plausibly dated from 1471; but Edward IV had not the political genius to work out in detailed administration the results of the victory which he owed to his military skill, and Richard III, who possessed the ability, made himself impossible as a king by the crimes he had to commit in order to reach the throne. The reconstruction of English government on a broader and firmer national basis was therefore left to Henry VII and the House of Tudor. CHAPTER IV THE PROGRESS OF NATIONALISM 1485-1603
