Richard of York fell at Sandal Hill, but the popularity which he had gained in Ireland descended to his son. In the bloody battle of Towton the flower of the Anglo-Irish Lancastrians fell, and their leader, the Earl of Ormonde, was taken and beheaded. His house suffered an eclipse from which it was destined to emerge with greater brilliancy than ever, and the rival family of Kildare became for a time supreme in the Pale. The native Irish everywhere advanced, and English law rapidly shrunk within the narrowest limits. A Parliament, held by the Earl of Desmond in 1465, enacted that every Irishman dwelling among the English in Dublin, Meath, Louth, and Kildare, should dress in the English fashion, shave his moustache, take the oath of allegiance within a year, and assume as a surname the name of a town, of a colour, or of a trade. In the Parliament of 1480, held by the Earl of Kildare, all trade between the Pale and the Irish was forbidden by law. The Parliament of Drogheda in 1468 had already passed an Act which declared that the castle of Ballymore Eustace, 'lying between the counties of Dublin and Kildare, among the O'Byrnes and O'Tooles, Irish enemies,' should be garrisoned by Englishmen only. The Eustaces, it was explained, had given it in charge to 'one Lawrence O'Bogan, an Irishman both by father and mother, who by nature would discover the secrets of the English.' Other Acts to a similar effect might be cited, and it may be said that the main object of Edward IV.'s government in Ireland was to separate the two races more completely.
