James Butler, 1st Duke of Ormonde

Lieutenant-General James FitzThomas Butler, 1st Duke of Ormond, KG, PC (19 October 1610 – 21 July 1688), was an Anglo-Irish statesman and soldier, known as Earl of Ormond from 1634 to 1642 and Marquess of Ormond from 1642 to 1661. Following the failure of the senior line of the Butler family, he was the second representative of the Kilcash branch to inherit the earldom.
His friend, the Earl of Strafford, secured his appointment as commander of the government army in Ireland. Following the outbreak of the Irish Rebellion of 1641, he led government forces against the Irish Catholic Confederation; when the First English Civil War began in August 1642, he supported the Royalists and in 1643 negotiated a ceasefire with the Confederation which allowed his troops to be transferred to England. Shortly before the Execution of Charles I in January 1649, he agreed the Second Ormonde Peace, an alliance between the Confederation and Royalist forces which fought against the Cromwellian conquest of Ireland.
During the 1650s he lived in exile on the continent with Charles II of England. After the Stuart Restoration in 1660, Ormond became a major figure in English and Irish politics, holding many high government offices such as Chancellor of the University of Oxford.
