To exalt the Lancastrian party, to depress the adherents of the house of York, were still the favorite objects of his pursuit; and through the whole course of his reign, he never forgot these early prepossessions.

Incapable from his natural temper of a more enlarged and more benevolent system of policy, he exposed himself to many present inconveniences, by too anxiously guarding against that future possible event, which might disjoin his title from that of the princess whom he espoused.

And while he treated the Yorkists as enemies, he soon rendered them such, and taught them to discuss that right to the crown, which he so carefully kept separate, and to perceive its weakness and invalidity.
To these passions of Henry, as well as to his suspicious politics, we are to ascribe the measures which he embraced two days after the battle of Bosworth.

Edward Plantagenet, earl of Warwick, son of the duke of Clarence, was detained in a kind of confinement at Sherif-Hutton, in Yorkshire, by the jealousy of his uncle Richard, whose title to the throne was inferior to that of the young prince.

Warwick had now reason to expect better treatment, as he was no obstacle to the succession either of Henry or Elizabeth; and from a youth of such tender years no danger could reasonably be apprehended.
