<P> On 9 April 1483, Edward IV of England died unexpectedly after an illness lasting around three weeks . At the time, Edward's son, the new King Edward V, was at Ludlow, and the dead king's brother, Richard, Duke of Gloucester, was at Middleham in Yorkshire . The news reached Gloucester around 15 April, although he may have been forewarned of Edward's illness . It is reported that he then went to York Minster to publicly "pledge his loyalty to his new king". The Croyland Chronicle states that, before his death, Edward IV designated his brother Gloucester as Lord Protector . Edward's request may not have mattered, however, since "as the precedent of Henry V showed, the council was not bound to follow the wishes of a dead king". </P> <P> Edward V and Gloucester set out for London from the west and north respectively, meeting at Stony Stratford on 29 April . The following morning, Gloucester arrested Edward's retinue including the boys' uncle, Anthony Woodville, 2nd Earl Rivers, and their half - brother Sir Richard Grey . They were sent to Pontefract Castle in Yorkshire where, on 25 June, they were beheaded . Gloucester then took possession of the prince himself, prompting Elizabeth Woodville to take her other son, Richard, Duke of York, and her daughters into sanctuary at Westminster Abbey . </P> <P> Edward V and Gloucester arrived in London together . Plans continued for Edward's coronation, but the date was postponed from 4 May to 25 June . On 19 May 1483 Edward was lodged in the Tower of London, then the traditional residence of monarchs prior to coronation . On 16 June, he was joined by his younger brother Richard, Duke of York, who was previously in sanctuary . At this point the date of Edward's coronation was indefinitely postponed by their uncle, Gloucester . On Sunday 22 June, a sermon was preached at Saint Paul's Cross claiming Gloucester to be the only legitimate heir of the House of York . On 25 June, "a group of lords, knights and gentlemen" petitioned Richard to take the throne . Both princes were subsequently declared illegitimate by Parliament; this was confirmed in 1484 by an Act of Parliament known as Titulus Regius . The act stated that Edward IV and Elizabeth Woodville's marriage was invalid because of Edward's pre-contract of marriage with Lady Eleanor Butler . Gloucester was crowned King Richard III of England on 3 July . The declaration of the boys' illegitimacy has been described by Rosemary Horrox as an ex post facto justification for Richard's accession . </P> <P> Dominic Mancini, an Italian friar who visited England in the 1480s and who was in London in the spring and summer of 1483, recorded that after Richard III seized the throne, Edward and his younger brother Richard were taken into the "inner apartments of the Tower" and then were seen less and less until they disappeared altogether . Mancini records that during this period Edward was regularly visited by a doctor, who reported that Edward, "like a victim prepared for sacrifice, sought remission of his sins by daily confession and penance, because he believed that death was facing him ." The Latin reference to "Argentinus medicus", was originally translated as "a Strasbourg doctor"; however, D.E. Rhodes suggests it may actually refer to "Doctor Argentine", whom Rhodes identifies as John Argentine, an English physician who would later serve as provost of King's College, Cambridge, and as doctor to Arthur, Prince of Wales, eldest son of King Henry VII of England (Henry Tudor). </P>
