GEORGE, duke of Clarence (1449-1478), younger son of Rich ard, duke of York, was born in Dublin on Oct. 21, 1449. Soon after his elder brother became king as Edward IV. in March 1461, he was created duke of Clarence, and his youth was no bar to his appointment as lord-lieutenant of Ireland in 1462. Clarence came under the influence of Richard Neville, earl of Warwick, and in July 1469 was married at Calais to the earl's elder daughter Isabella, although he had been a suitor for the hand of Mary of Burgundy. With his father-in-law he supported the rebels in the north of England. When their treachery was discovered Clarence fled to France. Returning to England with Warwick in Sept. 147o, he witnessed the restoration of Henry VI., when the crown was settled upon himself in case the male line of Henry's family became extinct. But a public reconciliation between the brothers took place when the king was besieging Warwick in Coventry, and Clarence then fought for the Yorkists at Barnet and Tewkes bury. After Warwick's death in April 1471 Clarence appears to have seized the whole of the vast estates of the earl, and in March 1472 was created by right of his wife earl of Warwick and Salisbury. The Warwick estates were eventually divided between Clarence and his younger brother Richard, duke of Gloucester (Richard III.) who married Warwick's younger daughter Anne. Clarence now sought to marry, as his second wife, Mary of Bur gundy, now duchess. To this marriage Edward IV. objected. He became convinced that Clarence was aiming at his throne. The duke was thrown into prison, and in Jan. 1478 the king unfolded the charges against his brother to the parliament. He had slandered the king; had received oaths of allegiance to him self and his heirs; had prepared for a new rebellion; and was in short incorrigible. Both houses of parliament passed the bill of attainder, and the sentence of death which followed was carried out on Feb. 17 or 18, 1478. It is uncertain what share Gloucester had in his brother's death; but soon after the event the rumour gained ground that Clarence had been drowned in a butt of malmsey wine. Two of the duke's children survived their father : Margaret, countess of Salisbury (1473-1541), and Edward, earl of Warwick (1475-99), who passed the greater part of his life in prison and was beheaded in Nov.
