George, Duke of Clarence, was Viceroy from 1461 to 1470, and again from 1472 till his mysterious death in 1478. Though born in Dublin, he never visited Ireland as a man, and the government was administered by a succession of Deputies. The fate of one of these Deputies, Thomas, eighth Earl of Desmond, deserves particular mention. John Tiptoft, Earl of Worcester, whose beautiful Latinity had moved Pope Æneas Sylvius to tears, was entrusted with the government in 1467, and he assembled a Parliament in which Desmond and Kildare were attainted. Kildare escaped to England, and procured a reversal of the attainder, but Desmond was enticed to Drogheda, and there beheaded. The ostensible cause for this severity is declared by an unpublished statute to have been 'alliance, fosterage, and alterage with the King's Irish enemies, and furnishing them with horses, harness, and arms, and supporting them against the King's loyal subjects.' The Anglo-Irish tradition attributes it to the vengeance of Queen Elizabeth Woodville, whose marriage Desmond had opposed. According to Russell, he told Edward that Sir John Grey's widow was too mean a match for him, that he needed allies sorely, and that he had better cast her off and link himself with some powerful prince. By this account the Queen stole the royal signet, and transmitted a secret order for the Earl's death to Ireland. Three years later Worcester was taken and beheaded during the short Lancastrian restoration; and this quite disposes of Russell's statement that King Edward 'struck his head from his neck to make satisfaction to the angry ghost of Desmond.' What is historically important in Desmond's execution is that it gave his successors an excuse for not attending Parliaments or entering walled towns. Their claim to legal exemption was not indeed allowed, but it may have had considerable effect on their conduct.[38] [Sidenote: Under Edward IV. and Richard III. the House of Kildare is all-powerful.
