On May 15, 1346, Butler marries Elizabeth Darcy, daughter of Sir John Darcy and Joan de Burgh. They have five children: James Butler, 3rd Earl of Ormond (1362-1405), Thomas Butler (1359-1396), Justice of Cork, Eleanor Butler (1350-1392), Joan Butler (1360-1393), and Ralph Butler (1356-1367).
In the 1360s Butler clashes with Maurice FitzGerald, 4th Earl of Kildare. In 1364 the Irish House of Commons sends a delegation to England, headed by Kildare, to complain of misgovernment, and to ask for the removal of “corrupt” officials, some of whom have links to Butler. A number of these officials are removed, but Butler’s position is not seriously threatened.
Butler is Lord Justice by July 24, 1376, with a salary of £500 per year, in which office he is continued by King Richard II of England. On April 2, 1372, he is made constable of Dublin Castle, with the fee of £18 5s per year. He is summoned to the Parliaments held by Richard II.
James Butler dies October 18, 1382 at Knocktopher Castle in Kilkenny, Leinster, near which he had founded a priory for Carmelite friars in 1356. He is buried in St. Canice’s Cathedral, Kilkenny.
By 1326 FitzGerald’s influence is such that there are rumours of a conspiracy to make him King of Ireland. Modern historians tend to dismiss the story, on the ground that the alleged conspirators were other magnates who were more interested in increasing their own power than aggrandising FitzGerald.
FitzGerald is created Earl of Desmond by Letters Patent dated at Gloucester, England, August 27, 1329, by which patent also the county palatine of Kerry is confirmed to him and his male heirs, to hold of the Crown by the service of one knight’s fee. This is part of a Crown policy of attempting to win the support of the magnates by conferring earldoms on them.
In January 1330 FitzGerald is summoned by Sir John Darcy, Lord Justice of Ireland, to fight armed Irish rebels, with a promise of the King’s pay. It is FitzGerald who introduces the practice of Coigne and Livery, the quartering of troops on the inhabitants of the district they are sent to protect.
Accepting the King’s proposal, in addition to dealing with Munster and Leinster, FitzGerald routs the O’Nolans and O’Murroughs and burns their lands in County Wicklow and forces them to give hostages. He recovers the castle of Ley from the O’Dempsies, and has a liberate of £100 sterling dated at Drogheda August 24, 1335, in return for the expense he has incurred in bringing his men-at-arms, hobelars, and foot-soldiers, from various parts of Munster to Drogheda, and there, with Lord Justice Darcy, disperses the King’s enemies.
In 1331 there are further rumours of an attempt to make him King. Although there seems to be no foundation for them, the Crown takes them seriously enough to imprison FitzGerald for several months. He is released when a number of fellow nobles stand surety for his good behaviour.
In 1339 FitzGerald is engaged against Irish rebels in County Kerry where it is said he slays 1,400 men, and takes Nicholas, Lord of Kerry, prisoner, keeping him confined until he dies as punishment for siding with the rebels against the Crown.
The same year FitzGerald is present in the parliament held in Dublin. He is summoned by Writ dated at Westminster July 10, 1344, with Maurice, Earl of Kildare, and others, to attend the King at Portsmouth “on the octaves of the nativity of the Virgin Mary,” with twenty men-at-arms and fifty hobelars, at his own expense, to assist in the war against Philip V of France.
FitzGerald, who has long been acting “with a certain disregard for the niceties of the law” now decides on open rebellion. In 1345 he presides at an assembly of Anglo-Irish magnates at Callan, County Kilkenny, ignores a summons to attend the Irish Parliament and attacks Nenagh. He is a formidable opponent, and for the next two years his defeat is the main preoccupation of the Crown. He surrenders on a promise that his life will be spared. He is imprisoned and his lands forfeited. He is allowed to go under guard to England to answer the charges against him.
By no means for the last time, the Crown evidently decides that it cannot govern Ireland without the magnates’ support. In 1348 FitzGerald is released and pardoned in 1349. His loyalty does not seem to have been in question during the last years of his life.
In July 1355 FitzGerald is appointed Lord Justice of Ireland for life, dying, however, the following January in Dublin Castle. He is interred in the Church of the Friars-Preachers in Tralee.
