Secondly, Parliament also had a longstanding commitment to re-conquer Ireland dating back to the Irish Rebellion of 1641. Even if the Irish Confederates had not allied themselves with the Royalists, it is likely that the English Parliament would have eventually tried to invade the country to crush Catholic power there. They had sent Parliamentary forces to Ireland throughout the Wars of the Three Kingdoms (most of them under Michael Jones in 1647). They viewed Ireland as part of the territory governed by right by the Kingdom of England and only temporarily out of its control since the Rebellion of 1641. Many Parliamentarians wished to punish the Irish for atrocities against the mainly Scottish Protestant settlers during the 1641 Uprising. Furthermore, some Irish towns (notably Wexford and Waterford) had acted as bases from which privateers had attacked English shipping throughout the 1640s.
