House of York
Though initially slow to keep his promise, Henry VII acknowledged the necessity of marrying Elizabeth of York to ensure the stability of his rule and weaken the claims of other surviving members of the House of York. It seems Henry wished to be seen as ruling in his own right, having claimed the throne by right of conquest and not by his marriage to the "de facto" heiress of the House of York. He had no intention of sharing power. He consequently chose to be crowned on 30 October 1485, before his marriage.
