Many believe that killing the princes would have actually been unnecessary for Richard Duke of Gloucester to become King. In June of 1483, before the disappearance of the two princes, Richard issued the Titulus Regius, which was a document explaining that the two princes were illegitimate and therefore had no claim to the throne
. This document allowed for Richard to ascend to the throne while the two princes still lived. If Richard had already guaranteed the throne for himself, he would have had no need to murder the two princes. This act would have been unnecessary and would damage his reputation.
