Richard, Duke of Gloucester was Edward V’s uncle and protector, but worked to have the Princes declared illegitimate. Although he succeeded in taking the crown for himself, he may have decided to murder the brothers to prevent them or their supporters from taking it back.
Years after the disappearance, James Tyrrell confessed to killing the boys on Richard’s orders. Sir Thomas More recounted the confession in his History of King Richard III and wrote that the Princes’ bodies were buried underneath a staircase. However, the confession was made under torture.
He has historically been blamed for their deaths. Though some believe he was unfairly maligned by his successors.
