Owing to the civil war that raged in England during the latter portion of the fifteenth century the English colonists were left entirely without support, and being divided among themselves, the Geraldines favouring the House of York, and the Ormonds, the House of Lancaster, they were almost powerless to resist the encroachments of the native princes. Nor did the accession of Henry VII. lead to a combined effort for the restoration of English authority. The welcome given by so many of the Anglo-Irish, both laymen and clerics, to the two pretenders, Simnel and Warbeck, and the efforts the king was obliged to make to defend his throne against these claimants, made it impossible for him to undertake the conquest of the country. As a result, the sphere of English influence in Ireland, or the Pale, as it was called, became gradually more restricted. The frantic efforts made by the Parliament held at Drogheda (1494, Poynings' Parliament) to protect the English territory from invasion by the erection "of a double ditch six feet high" is the best evidence that the conquest of the country still awaited completion.[1] In the early years of the reign of Henry VIII. the Pale embraced only portions of the present counties of Dublin, Louth, Meath and Kildare, or to be more accurate, it was bounded by a line drawn from Dundalk through Ardee, Kells, Kilcock, Clane, Naas, Kilcullen, Ballymore-Eustace, Rathcoole, Tallaght, and Dalkey. Within this limited area the inhabitants were not safe from invasion and spoliation unless they agreed to purchase their security by the payment of an annual tribute to the neighbouring Irish princes; and outside it, even in the cities held by Norman settlers and in the territories owned by Norman barons, the king's writ did not run.[2]
