he inherited the crown aged 9 months) had ended with his coronation aged seven. Richard, however, repeatedly postponed the coronation. On 22 June, Ralph Shaa preached a sermon declaring that Edward IV had already been contracted to marry Lady Eleanor Butler when he married Elizabeth Woodville, thereby rendering his marriage to Elizabeth invalid and their children together illegitimate. The children of Richard's older brother George, Duke of Clarence, were barred from the throne by their father's attainder, and therefore, on 25 June, an assembly of Lords and Commons declared Richard to be the legitimate king (this was later confirmed by the act of parliament Titulus Regius). The following day he acceded to the throne as King Richard III. Disappearance Dominic Mancini recorded that after Richard III seized the throne, Edward and his brother Richard were taken into the "inner apartments of the Tower" and then were seen less and less until the end of the summer to the autumn of 1483, when they disappeared from public view altogether. During this period Mancini records that 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 princes' fate after their disappearance remains unknown, but the most widely accepted theory is that they were murdered on the orders of their uncle, King Richard. Thomas More wrote that they were smothered to death with their pillows, and his account forms the basis of William Shakespeare's play Richard III, in which Tyrrell murders the princes on Richard's orders. In the absence of hard evidence a number of other theories have been put forward, of which the most widely discussed are that they were murdered on the orders of Henry Stafford, 2nd Duke of Buckingham, or by Henry Tudor. However, A. J. Pollard points out that these theories are less plausible than
