Lord of Connaught (Irish: Tighearna Connacht) was a title used by several Norman barons in Ireland. Granted to William de Burgh, the lordship was claimed by his son, Richard Mor de Burgh, and his descendants.
Conquest
During the Norman invasion of Ireland, William de Burgh (d.1206) was apparently granted Connacht, but never took possession of it. It remained in the hands of native kings until 1224, when his son, Richard Mor de Burgh, claimed it on the basis of his father's grant. Richard's uncle Hubert de Burgh was then Justiciar of Ireland and upheld the claim in 1227. Richard called upon the feudal levies of Ireland and conquered Connacht (1235), assuming the title Lord of Connaught.
