James Butler, 1st Duke of Ormonde KG, PC (19 October 1610 – 21 July 1688) was an Anglo-Irish statesman and soldier, known as Earl of Ormonde from 1634 to 1642 and Marquess of Ormonde from 1642 to 1661. Following the failure of the senior line of the Butler family, he was the second of the Kilcash branch to inherit the earldom. His friend, the 1st Earl of Strafford, caused him to be appointed the commander of the Cavalier forces in Ireland. From 1641 to 1647, he led the fighting against the Irish Catholic Confederation. From 1649 to 1650 he was leading commander of the Royalist forces fighting against the Cromwellian conquest of Ireland. In the 1650s he lived in exile in Europe with Charles II of England. Upon the restoration of Charles II to the British throne in 1660, Ormonde became a major figure in English and Irish politics, holding many high government offices.
