Alan of Galloway (1186-1236) was Duke of Galloway from 12 December 1200 to 1236, succeeding Lochlann of Galloway. He was the last legitimate Duke of Galloway, and his son-in-law John I de Balliol succeeded him as Lord.
Biography[]
Alan was born in 1186, the son of Lord Lochlann of Galloway and the brother of Thomas of Galloway. He succeeded his father as Lord of Galloway and Constable of Scotland in 1200, and he became one of the most powerful magnates in the Kingdom of Scotland due to his large landholdings in both Scotland and England. He and his brother Thomas participated in the English colonization of Ulster, and he also helped the Scottish crown defeat rival claimants to the throne. His intervention in the civil wars of Sudreyjar provoked King Haakon IV of Norway into intervening in the British Isles. Alan died in 1236, and King Alexander II of Galloway partitioned his lands between his sons-in-law, as he had no legitimate male heirs.
