Siege of Drogheda Ends

Date: September 11, 1649 • Location: Drogheda, Ireland

The Cromwellian conquest of Ireland, 1649 to 1653, refers to the defeat of the Irish Catholic Confederation and their allies, by forces of the Commonwealth of England, led by Oliver Cromwell. It concluded the 1641 to 1653 Irish Confederate Wars and 1639 to 1653 Wars of the Three Kingdoms, which modern estimates generally agree led to an overall decline in the pre-1641 Irish population of over 15%, due to war, famine and disease.
