Walter de Burgh, 1st Earl of Ulster

Walter de Burgh (c. 1230 – 28 July 1271) was 2nd Lord of Connaught and 1st Earl of Ulster (2nd creation).

De Burgh was the second son of Richard Mór de Burgh, 1st Lord of Connaught and Egidia de Lacy. He founded Athassel Priory.

In 1243, he succeeded his father as Lord of Connacht, and was created Earl of Ulster as well in 1264. In 1270, he and Walter de Ufford, the Justiciar of Ireland, were defeated by Aedh mac Felim Ua Conchobair at Ath an Chip.

He married Aveline, daughter of Sir John FitzGeoffrey, Justiciar of Ireland, by his wife, Isabel Bigod. In a royal order from Westminster in September 1247, Sir John FitzGeoffrey was charged by the King with seizing the lands of Walter de Burgh's older brother Richard, who had died. The de Burgh lands in Connaught were being held by de Burgh, John de Livet, likely the son of Gilbert de Lyvet, one of the earliest Lord Mayors of Dublin and Marmaduke de Eschales (Scales).

He died, aged about 40, in Galway, and was succeeded by his eldest son, Richard Óg de Burgh, 2nd Earl of Ulster (The Red Earl of Ulster). Other children were three sons, Theobald, William and Thomas, and daughter, Egidia who married Sir James Stewart (1260–1309), High Steward of Scotland.[1]
