Edward V (2 November 1470 – c.mid-1483)[1][2] was King of England from 9 April to 25 June 1483. He succeeded his father, Edward IV, upon the latter's death. Edward V was never crowned, and his brief reign was dominated by the influence of his uncle and Lord Protector, the Duke of Gloucester, who deposed him to reign as King Richard III; this was confirmed by the Titulus Regius, an Act of Parliament which denounced any further claims through Edward IV's heirs by delegitimising Edward V and all of his siblings. This was later repealed by Henry VII, who wished to legitimise his reign by marrying Elizabeth of York, Edward's eldest sister.

Edward V and his younger brother, Richard of Shrewsbury, are known as the "Princes in the Tower". They disappeared after being sent to heavily guarded royal lodgings in the Tower of London. Responsibility for their disappearance and presumed deaths is widely attributed to Richard III, who sent them to the Tower, but the lack of conclusive evidence and conflicting contemporary accounts allow for other possibilities.

Titulus Regius ("royal title" in Latin) is a statute of the Parliament of England issued in 1484 by which the title of King of England was given to Richard III.

The act ratified the declaration of the Lords and the members of the House of Commons a year earlier that the marriage of Edward IV of England to Elizabeth Woodville had been invalid and so their children, including Edward, Richard and Elizabeth, were illegitimate and thus debarred from the throne. Their uncle Richard III had been proclaimed the rightful king. Since the Lords and the Commons had not been officially convened as a parliament, doubts had arisen as to its validity and so when Parliament convened, it enacted the declaration as a law.
