The conflict began with the Irish Rebellion of 1641, when Irish Catholics sought to end anti-Catholic discrimination, increase self-governance, and halt the Plantations of Ireland. They feared invasion by anti-Catholic Parliamentarians and Scottish Covenanters. The rebellion quickly became an ethnic conflict between Irish Catholics and Protestant colonists, marked by massacres and ethnic cleansing in Ulster.
The Irish Catholic Confederation, formed in May 1642, governed most of Ireland and fought Royalists, Parliamentarians, and Scottish Covenanters simultaneously. In August 1649, Oliver Cromwell led a Parliamentarian army into Ireland, besieging towns and massacring soldiers and civilians at Drogheda and Wexford. The Confederate–Royalist alliance collapsed with the fall of Kilkenny in 1650 and Galway in 1652, with guerrilla resistance persisting until April 1653.
Following their defeat, Ireland was occupied and annexed by the English Commonwealth. Catholicism was suppressed, most Catholic-owned land was confiscated, and tens of thousands of Irish rebels were transported as indentured servants to the Caribbean or Virginia, or joined Catholic armies in Europe. The war also contributed to sparking the English Civil War and reshaped the religious and landowning structure of Ireland for generations.
