VII had the Act of Titulus Regius repealed, thereby legitimising anew the children of Edward IV, and acknowledging Edward V as his predecessor. Though Richard III was regarded as a usurper, his reign was not ignored. Henry and Elizabeth required a papal dispensation to wed because of Canon Law frowning upon "affinity": Henry and Elizabeth were descended from, respectively, John of Gaunt and his younger brother Edmund in the 4th degree, an issue that had caused much dispute and bloodshed as to which claim was superior. Two applications were sent, the first more locally, and the second one was slow in reaching Rome and slow to return with the response of the Pope.

This was a marriage of 'faithful love', of mutual attraction, affection and respect, from which the king seems to have drawn great strength."
