According to another school the real key to the problem is simply the question of the succession to the crown. If the wedlock of Henry VI. and Margaret of Anjou had been fruitful during the first few years after their marriage, no one would have raised the question of a change of dynasty. But when they remained childless for seven years, and strong suspicion arose that there was a project on foot to declare the Beauforts heirs to the throne, the claim of Richard of York, as the representative of the houses of Clarence and March, was raised by those who viewed the possible accession of the incapable and unpopular Somerset with terror and dislike. When once the claims of York had been displayed and stated by his imprudent partisan, Thomas Yonge, in the parliament of 1451, there was no possibility of hiding the fact that in the strict legitimate line of succession he had a better claim than the reigning king. He disavowed any pretensions to the crown for nine years; it was only in 1460 that he set forth his title with his own mouth. But his friends and followers were not so discreet; hence when a son was at last born to Henry and Margaret, in 1453, the succession question was already in the air and could no longer be ignored. If the claim of York was superior to that of Lancaster in the eyes of a considerable part of the nation, it was no longer possible to consider the problem solved by the birth of a direct heir to the actual occupant of the throne. Though Duke Richard behaved in the most correct fashion, acknowledged the infant Edward as prince of Wales, and made no attempt to assert dynastic claims during his two regencies in 1454 and 1455-1456, yet the queen and her partisans already looked upon him as a pretender to the throne. It is this fact which accounts for the growing bitterness of the Yorkist and Lancastrian parties during the last years of Henry VI. Margaret believed herself to be defending the rights of her son against a would-be usurper. Duke Richard, on the other hand, considered himself as wrongfully oppressed, and excluded from his legitimate position as a prince of the blood and a chief councillor of the crown. Nor can there be any doubt that the queen took every opportunity of showing her suspicion of him, and deliberately kept him and his friends from sharing in the administration of the realm. This might have been more tolerable if the Lancastrian party had shown any governing power; but both while Somerset was their leader, down to his death in the first battle of St Albans, and while in 1456-1459 Exeter, Wiltshire, Shrewsbury and Beaumont were the queen's trusted agents, the condition of England was deplorable. As a contemporary chronicler wrote, "the realm was out of all good governance--as it has been many days before: the king was simple, and led by covetous councillors, and owed more than he was worth. His debts increased daily, but payment was there none, for all
