Henry VI was murdered in the Tower of London during the night of 21–22 May 1471. Earlier on 21 May Edward IV had entered London in triumph, following his victory at the Battle of Tewkesbury on 4 May. Henry's only son, Prince Edward of Westminster, had been killed at or shortly after the battle, and his death evidently sealed the fate of his father. Edward IV had Henry buried out of the way at Chertsey abbey, doubtless in part to forestall veneration of his body. Nonetheless, rumours of miracles performed at Henry's tomb began to spread and he became the focus of an extremely popular cult. This cult provides abundant evidence for the great value which medieval people continued to find in saints on the eve of the Reformation. However, initial academic approaches to it emphasised its political dimensions, exploring the ways in which devotion to Henry (in common with devotion to men such as Simon de Montfort, Thomas of Lancaster and Richard Scrope) formed an expression of opposition to the crown. Tudor interest in the cult was clearly political, involving the systematic recording of Henry's miracles as part of an attempt to have him canonised. But it is far from certain that political motives lay behind the increasing regularity with which people sought Henry VI's intercession, particularly once Richard III moved his body to a prestigious location, St George's chapel, Windsor, in August 1484.
