Decisive English Parliamentarian victory

Irish Catholic Confederation

English Parliamentarian

The Cromwellian conquest of Ireland or Cromwellian war in Ireland (1649–53) refers to the conquest of Ireland by the forces of the English Parliament, led by Oliver Cromwell, during the Wars of the Three Kingdoms. Cromwell invaded Ireland with his New Model Army on behalf of England's Rump Parliament in August 1649.

Following the Irish Rebellion of 1641, most of Ireland came under the control of the Irish Catholic Confederation. In early 1649, the Confederates allied with the English Royalists, who had been defeated by the Parliamentarians in the English Civil War. By May 1652, Cromwell's Parliamentarian army had defeated the Confederate and Royalist coalition in Ireland and occupied the country—bringing to an end the Irish Confederate Wars (or Eleven Years' War). However, guerrilla warfare continued for a further year. Cromwell passed a series of Penal Laws against Roman Catholics (the vast majority of the population) and confiscated large amounts of their land.
