Aonghas Óg

Aonghas Óg (died 1490) was a Scottish nobleman who was the last independent Lord of the Isles. Aonghas became a rebel against both his father and against the Scottish crown, in a civil clan war which would see the end of the independent Lordship of the Isles.

Aonghas was born the bastard son of John of Islay, Earl of Ross (Eoin). In time, Aonghas would become a rebel against both his father and against the Scottish crown. He is not to be confused with his namesake, Aonghas Óg, Lord of Islay, who fought alongside Robert the Bruce.

After the discovery in 1476 of a secret treaty made by John of Islay with Edward IV of England by James III of Scotland, James stripped Ross of his earldom, as well as the sheriffdoms of Nairn and Inverness, and the lordships of Kintyre and Knapdale, but confirmed Eoin with the remainder of his lands and the title Lord of the Isles. It appears that Aonghas, as Eoin's heir, was not prepared to accept this settlement. Aonghas campaigned to regain Ross and the other lost dominions. At first he may have been supported by his father, but this did not last. Aonghas married Isobella Campbell daughter of Colin Campbell, 1st Earl of Argyll.

Eoin, his prestige in tatters, was driven from Islay by his son. Eoin managed to gather support among the MacGill'Eain ("MacLean") kindred of Duart, the MacLeoid kindred of Lewis and Harris, and MacNeill kindred of Barra, as well as the Scottish crown and John Stewart, Earl of Atholl; but Aonghas had the important support of Domhnall Ballach and the rest of the MacDomhnaill kindred.
