Lordofthe Isles
Lord of the Isles, a title borne by certain chieftains in years gone by of the Western Isles of Scotland. The title - though not assumed till later - seems to have had its origin in the gift of Arran and Bute by David I., in 1135, to the Lord of Argyll. He was killed by Malcolm IV., in 1164, and his sons held the southern isles, nominally under the Scottish Crown. It was John, son of Angus of Isla, who first assumed the title. After intrigues and reverses of various kinds the line came to an end in the person of John, fourth and last lord, who was deprived by James IV., in 1493, and in 1540 the title was annexed to the Crown of Scotland.
