In 1641 a major rebellion broke out in Ireland. The Catholics inhabitants, while proclaiming their loyalty to King Charles I, rose up against the Parliament of England and its allies in the Irish government in Dublin. The rebellion spread across Ireland, drawing in both the Gaelic Irish and Anglo-Irish Catholics. In response to some massacres of Protestants, forces of Scottish and English troops were raised and arrived to support the Irish Protestants. The following war lasted for more than a decade.
