The Cromwellian Period
During the 1650s the remaining Gaelic landownership in Ulster was almost wiped out. Large swathes of land were confiscated from the Irish gentry as a punishment for their rebellion and granted to British settlers. For a time Scottish landowners in Ulster were also in a difficult situation with the threat of confiscation also hanging over them for their support of the royalist cause. Eventually, however, their possessions were secured on payment of heavy fines. Cromwell died in 1658 and in 1660 the monarchy was restored. The new king, Charles II, was faced with the difficulty of having to find land for those Catholics who had remained loyal to the Crown during the previous twenty years. Several Scottish Catholics – the Marquess of Antrim and the Hamiltons in Strabane barony, County Tyrone, were restored to the estates they had held prior to 1641. Apart from this there were relatively few changes to the land settlement laid down by Cromwell.
Migration to the north of Ireland in the 1650s was encouraged by low rents in the aftermath of a decade of warfare. In the 1670s migration was encouraged by the Covenanter disturbances in Scotland. These fresh migrations were having a noticeable impact on local demographics. About 1670 Oliver Plunkett, Catholic archbishop of Armagh, noted that the city of Armagh had a population of approximately 3,000 persons, ‘almost all Scottish or English, with very few Irish’.
