Princes in the Tower "The Princes in the Tower" is an expression frequently used to refer to Edward V, King of England and Richard of Shrewsbury, Duke of York. The two brothers were the only sons of Edward IV of England and Elizabeth Woodville surviving at the time of their father's death in 1483. When they were 12 and 9 years old, respectively, they were lodged in the Tower of London by the man appointed to look after them, their uncle, the Lord Protector: Richard, Duke of Gloucester. This was supposedly in preparation for Edward's forthcoming coronation as king. However, Richard took the throne for himself and the boys disappeared.
Roger Mortimer, 1st Earl of March Roger Mortimer, 3rd Baron Mortimer, 1st Earl of March (25 April 1287 – 29 November 1330), was an English nobleman and powerful Marcher lord who gained many estates in the Welsh Marches and Ireland following his advantageous marriage to the wealthy heiress Joan de Geneville, 2nd Baroness Geneville. In November 1316, he was appointed Lord Lieutenant of Ireland. He was imprisoned in the Tower of London in 1322 for having led the Marcher lords in a revolt against King Edward II in what became known as the Despenser War. He later escaped to France, where he was joined by Edward's queen consort Isabella, whom he took as his mistress. After he and Isabella led a successful invasion and rebellion, Edward was subsequently deposed; Mortimer allegedly arranged his murder at Berkeley Castle. For three years, Mortimer was "de facto" ruler of England before being himself overthrown by Edward's eldest son, Edward III. Accused of assuming royal power and other crimes, Mortimer was executed by hanging at Tyburn.
