CLARENCE, DUKES OF. The early history of this Eng lish title is identical with that of the family of Clare, earls of Gloucester, who are sometimes called earls of Clare, of which word Clarence is a later form. The first duke of Clarence was Lionel of Antwerp (see below), third son of Edward III., who was created duke in 1362, and whose wife Elizabeth was a direct descendant of the Clares, the "Honour of Clare" being among the lands which she brought to her husband. When Lionel died with out sons in 1368 the title became extinct; but in 1412 it was re vived in favour of Thomas (see below), the second son of Henry IV. The third creation of a duke of Clarence took place in 1461, and was in favour of George (see below), brother of the king Edward IV. When this duke, accused by the king, was attainted and killed in 1478, his titles and estates were forfeited. There appears to have been no other creation of a duke of Clarence until 1789, when William, third son of George III., was made a peer under this title. Having merged in the Crown when William be came king of Great Britain and Ireland in 1830, the title of duke of Clarence was again revived in 1890 in favour of Albert Victor (1864-92), the elder son of King Edward VII., then prince of Wales, only to become extinct for the fifth time on his death in 1892.
