The Irish Confederate Wars, also called the Eleven Years' War (derived from the Irish language name Cogadh na hAon Bhliana Déag), took place in Ireland between 1641 and 1653. It was the Irish theatre of the Wars of the Three Kingdoms – a series of civil wars in the kingdoms of Ireland, England and Scotland (all ruled by Charles I). The conflict in Ireland essentially started by pitting the native Irish Catholics against English and Scottish Protestant colonists and their supporters, and ended with Royalists, Irish Catholics and Scottish Presbyterians fighting the ultimate winners, the English Parliament. It was both a religious and an ethnic conflict – fought over who would govern Ireland, whether it would be governed from England, which ethnic and religious group would own most of the land, and which religion would predominate in the country. It was the most destructive conflict in Irish history.

The war in Ireland began with the Rebellion of 1641 in Ulster in October, during which many Scots and English Protestant settlers were killed. The rebellion spread throughout the country and at Kilkenny in 1642 the Association of The Confederate Catholics of Ireland was formed to organise the Catholic war effort. The Confederation was essentially an independent state and was a coalition of all shades of Irish Catholic society, both Gaelic and Old English. The Irish Confederates professed to side with the English Cavaliers during the ensuing civil wars, but mostly fought their own war in defence of the Catholic landed class' interests.
