Abstract
In October 1641, Catholic grievances over plantation, exclusion and religious constraints combined with Stuart political instability to trigger rebellion in Ireland. A planned seizure of Dublin Castle failed, but Sir Phelim O’Neill’s Ulster rising captured Dungannon and Charlemont. His proclamation professed loyalty to Charles I and protection for Protestants, while a later forged royal commission fuelled confusion. The conflict brought flight, plunder, killings, dispossession and winter hardship, alongside retaliatory violence. Testimony in the 1641 Depositions records crisis but requires critical reading. Fighting spread towards Dublin, Leinster and Munster, intensified English and Scottish political conflict, and left Ireland fractured without settlement.

Abstract
In 1642, Ireland’s uprising became organised war amid the Wars of the Three Kingdoms. Catholic leaders united Gaelic and Old English interests around defence of worship, property and liberties, while professing loyalty to Charles I. Synods at Kells and Kilkenny promoted an oath of association. In October, the Kilkenny General Assembly established a Supreme Council, subordinate councils, military administration and taxation, creating a fragile Catholic government. Royalist, Protestant and Scottish forces retained key territories; defeats at Kilrush and Liscarroll checked Catholic arms. Owen Roe O’Neill’s return aided Ulster’s future resistance. War brought displacement, requisitioning and violence to all communities nationwide.

In 1643, Ireland’s conflict within the Wars of the Three Kingdoms continued despite shifting military and political circumstances. Confederate forces captured Birr but suffered defeat at New Ross, while achieving a Munster success at Cloughleagh. Supply shortages, taxation, agricultural regulation, trade controls and anti-Catholic measures revealed wartime pressures around Dublin. On 15 September, Ormond and Confederate commissioners agreed the Sigginstown Cessation, a year-long armistice involving territorial arrangements, diplomacy and payments. It excluded Scottish Covenanting forces in Ulster and resolved neither religion nor landownership. The truce intensified Confederate debates, enabled northern planning, and coincided with Mícheál Ó Cléirigh’s work at Louvain.

Abstract
In 1644, Confederate Ireland governed extensive territory from Kilkenny while negotiating with Charles I’s administration for Catholic worship, property, officeholding and parliamentary freedoms. Ormond pursued peace, but no settlement emerged. A major Confederate expedition under Castlehaven and Owen Roe O’Neill failed to dislodge Robert Monro’s Covenanter forces in Ulster, exposing divisions and supply weaknesses. Meanwhile, Alasdair MacColla’s troops crossed to Scotland to support royalists, prompting Westminster’s no-quarter ordinance. In Munster, Lord Inchiquin repudiated the cessation, joined Parliament, and expelled Catholics from Cork, Youghal and Kinsale. Trade continued amid war, but requisitioning, displacement and insecurity afflicted civilians deeply throughout the island.

In 1645, the Catholic Confederation strengthened its position by capturing Duncannon Fort after Thomas Preston’s siege, gaining control over an important Waterford Harbour defence but not coastal supremacy. Secret negotiations between Edward Somerset, earl of Glamorgan, and Confederate representatives promised religious concessions and troops for Charles I, but their disclosure damaged royalist prospects. Archbishop Malachy Ó Caollaidhe died amid Connacht fighting. Papal nuncio Giovanni Battista Rinuccini arrived with money, arms and authority, intensifying demands for enforceable Catholic guarantees. War imposed severe local burdens, while Jesuits founded a Galway school and John Colgan published a major saints’ collection at Leuven abroad.

Abstract
In 1646, the Catholic Confederation reached its military zenith but became divided over peace with Charles I. Owen Roe O’Neill’s victory over Scottish Covenanters at Benburb, Preston’s Connacht operations, and the capture of Bunratty strengthened hopes of securing Catholic religious and political guarantees. The First Ormond Peace, agreed secretly with the royalist lord lieutenant, offered insufficient protections and provoked clerical, military and popular resistance. Papal nuncio Giovanni Battista Rinuccini led opposition, overthrowing the agreement and remodelling Confederate government. A failed advance on Dublin exposed rivalries, weak supply and divided command. Kilkenny’s Catholic print culture also articulated suffering, rights and legitimacy.

In 1647, the Catholic Confederation’s position collapsed after political division, logistical weakness and military reverses. Parliament gained Dublin when Ormond transferred the city in June, providing a strategic base. Michael Jones destroyed Thomas Preston’s Leinster army at Dungan’s Hill in August, ending any prospect of taking Dublin. In Munster, Inchiquin’s forces devastated communities and stormed Cashel, killing defenders and civilians, plundering the religious complex and deepening Catholic fears. In November, Inchiquin defeated Taaffe’s army at Knocknanuss, killing Alasdair MacColla. Although Kilkenny and O’Neill’s Ulster army survived, these disasters encouraged royalist negotiation and transformed Confederate ambitions into a struggle for survival.

Abstract
In 1648, the Catholic Confederation of Ireland fractured over the Dungarvan truce with Murrough O’Brien, Lord Inchiquin, newly aligned with Charles I. Exhaustion after 1647 defeats led moderates to seek a royalist coalition and negotiations with Ormond, despite Inchiquin’s destructive record. Papal nuncio Rinuccini condemned the truce, censuring supporters and joining Owen Roe O’Neill’s resistance. Rival Confederate armies campaigned without decisive battle, burdening civilians suffering requisition and scarcity. The Kilkenny assembly marginalised O’Neill, while Ormond’s return and Rome’s limited aid strengthened accommodation. O’Neill’s ceasefire with parliamentarian Michael Jones revealed division. Winter brought coalition, not peace, before the 1649 Ormond settlement.

Abstract
In 1649, the second Ormond peace united Confederate Catholics and royalists against the English Commonwealth, but exclusion of Owen Roe O’Neill exposed deep divisions. Ormond’s defeat by Michael Jones at Rathmines on 2 August secured Dublin for parliament, enabling Oliver Cromwell’s landing with the New Model Army and naval support. At Drogheda in September and Wexford in October, stormings produced exceptional killings, including civilians and clergy, and devastated resistance and trade. O’Neill’s death further weakened opposition. Cromwell failed to take Waterford before winter, but the year transformed the war, creating conditions for the later Cromwellian conquest and settlement in Ireland.

Abstract
In 1650, the Cromwellian conquest advanced despite continuing resistance in Connacht, Limerick and Ulster. Cromwell’s agreement with Protestant royalists weakened Ormond’s Catholic–royalist coalition. At Clonmel, Hugh Dubh O’Neill’s improvised inner defence repelled a costly assault, although shortages enabled the garrison’s escape and the town’s surrender. Broghill defeated a relief force at Macroom, while Scarrifholis destroyed the Ulster Catholic army and led to Heber MacMahon’s execution. After Cromwell departed, Henry Ireton captured plague-stricken Waterford and Duncannon, pressured Athlone and failed before Limerick. Clergy repudiated Ormond; garrisons, blockade, disease and resource seizures established groundwork for further conquest and settlement in Ireland thereafter.
