Web Notes notes for Mortogh O'BRIEN King Of Thomond
He was King of Thomond from 1313, when his second cousin, King Diarmait Cleirech, died. He was co-King with his second cousin Donnchad from 1313-1316, when Donnchad was deposed, then he was sole king until his death in 1343.
From book "Kings and Queens of Britain" by David Williamson, p234: King of Thomond 1307-1343
Mortogh O'Brien, together with his brother, Donough, and his cousin, de Burgh, successfully laid siege to Lord Thomas de Clare, son on the Earl of Gloucester, in 1310 at Bunratty Castle, who had murdered his grand uncle by inviting him to Bunratty Castle as a friend, and after a great banquet, tearing him apart by tying him between two horses pulling in opposite directions and ripping his body asunder. He finally defeated and killed de Clare at the Battle of Dysert O'Dea in 1318, which battle finally expelled the English from Thomond.9
The political scenario was radically transformed and complicated in 1315 by the invasion of Robert de Bruce, King of Scotland, and his brother Edward. King Donogh and clan Brian elected to support Edward Bruce and to oppose the English settlement in Ireland. Richard de Clare was now an enemy of Donogh and clan Brian, while he had always opposed clan Turlough. Without the support of Richard de Clare King Donogh fled to Connaught and he later joined the Bruce camp. His rival Muirceartach was now supreme in Clare.
In 1317 the exiled King Donogh persuaded the Bruce brothers to invade Munster to drive the English from Thomond as well as his usurping cousin Muirceartach. Muirceartach joined de Clare, de Burgh and other Norman barons at Cashel to oppose their common enemy, but after reaching Castleconnell the Bruce army retreated towards Dublin, leaving King Donogh and his army behind. Muirceartach attended a parliament in Dublin and while he was there his brother Dermot determined to destroy clan Brian. At the battle of Corcomroe in 1317, Donogh and most of the clan Brian army were killed, his son Brian Bane escaped with a few followers and went to Tipperary. When Muirceartach returned from Dublin in 1317 almost all of Clare rallied to him, with the exception of Richard de Clare and his protégé Mahon O'Brian who acted as de Clare's agent in west Clare. De Clare again tried to divide the county between the feuding O'Brian's but Muirceartach refused to accept an imposed settlement from de Clare (who had always opposed clan Turlough). Muirceartach banished Mahon O'Briain and refused to accept any authority from de Clare. War was the only solution to this struggle between Muirceartach O'Briain and Richard de Clare for control of Thomond.
