Sligo Castle and Aed Brefnech
Archived: 24 October 2026
In 1310, Ireland remained politically fragmented despite Edward II’s lordship. At Kilkenny Parliament, John Wogan, Richard de Burgh and church leaders addressed disorder, revealing reliance on powerful magnates. In Connacht, Aed Brefnech Ó Conchobair’s destructive campaign against Mac Diarmata included killings, capture and burning; his allies then sacked Buninna Castle. Aed was subsequently murdered by mercenaries, allegedly bribed by William de Burgh, whose soldiers imposed oppressive quartering. Feidlim Ó Conchobair emerged as king of Connacht. Richard rebuilt Sligo Castle, asserting contested authority. The year also saw scholar Tanaide Ó Maelchonaire’s death, wine landing in Magh Cétné, and violence across Ireland.
