Burke Civil War
William Donn de Burgh, 3rd Earl of Ulster, was murdered by his household knights in June 1333. His only child, Elizabeth de Burgh (1332–1363), succeeded as Countess of Ulster and legal heir to the de Burgh estate as an infant. But because she was an infant, and a female, she was taken by her mother to England for safety.
Meanwhile, three members of the de Burgh family fought against each other in an attempt to preserve their own personal estates, and overall control of the massive de Burgh inheritance in Ireland. They were:
- Sir Edmond de Burgh of Castleconnell, only surviving uncle of the Brown Earl and senior member of the de Burgh dynasty.
- Sir Edmond Albanach de Burgh of north Connacht, a cousin of the Brown Earl and Sir Edmond of Castleconnell.
- Sir Uilleag de Burgh of south Connacht, chief of an illegitimate branch of the de Burghs.
Loss and divisions
The remaining de Burghs in Ireland fragmented into three distinct clans, all of which had several sub-septs. They were:
- Clan William Bourke of County Limerick
- Mac William Íochtar of County Mayo
- Mac William Uachtar/Clanricarde Burke of County Galway
