Richard Mór de Burgh, 1st Lord of Connacht (; ; c.1194–1242, or 1243), was a Hiberno-Norman aristocrat who was Seneschal of Munster and Justiciar of Ireland (1228–32). Background Richard Mór de Burgh was born towards the end of the year in 1193 (and came of age in 1214). He was the eldest son and heir of William de Burgh and his wife (daughter of Domnall Mór Ua Briain, King of Thomond). Richard's principal estate was in the barony of Loughrea where he built a castle in 1236 and a town was founded. He also founded Galway town and Ballinasloe. The islands on Lough Mask and Lough Orben were also part of his demesne. From the death of his father (1206) until he reached his majority and received his inheritance (1214), Richard was a ward of the crown of England. In 1215 he briefly served in the household of his uncle, Hubert de Burgh, Earl of Kent. In 1223 (and again in 1225) he was appointed Seneschal of Munster and keeper of Limerick Castle. Connacht In 1224, Richard claimed Connacht (which had been granted to his father but never, in fact, conquered by him): he asserted that the grant to the Gaelic king Cathal Crobdearg Ua Conchobair (after William de Burgh's death in 1206), had been on condition of faithful service and that the king's son, Aedh mac Cathal Crobdearg Ua Conchobair (who succeeded that year) had forfeited it. Richard had the favour of his uncle, Hubert, justiciar of England, and was later awarded Connacht (May 1227). Having been given custody of the counties of Cork and Waterford and all the crown lands of Decies and Desmond, he was appointed Justiciar of Ireland (1228–32). In 1230 he was able to send the King 2000 marks, the proceeds of a tax of one-sixteenth on ecclesiastical benefices. When, in 1232, his uncle Hubert's fell from grace, Richard was able to distance himself and avoid being campaigned against by Henry III. It was only in 1235, when he summoned the whole feudal host of the English lords and magnates to aid him, that he finally expelled the Gaelic king, Felim mac Cathal Crobderg Ua Conchobair, from Connacht. Richard and his lieutenants received great shares of land, while Felim was obliged to pay homage and was allowed to hold only five cantreds (in Roscommon), while Richard held the remaining 25 cantreds of Connacht in chief
