Scottish expedition into Argyll (1221–1222)

The Scottish expedition into Argyll (1221–1222) was a Scottish expedition into Argyll and the surrounding region. The expedition led by King Alexander II of Scotland, appears to have been undertaken to counter the threat of Clann Somhairle and alliances created between the Crovan dynasty of the Isle of Man and Ailean mac Lachlainn, Lord of Galloway and Constable of Scotland and old alliances with the Meic Uilleim and MacHeths. The sub kingdom of Argyll was brought into the Kingdom of Scotland, after expelling Ruaidhrí mac Raghnaill from the area and the submission and swearing of fealty given by Donnchadh of Argyll. Alexander II set about formalising Norman feudal law and Scottish administration of the area and ordered the building of royal castles at Dunoon, Cowal and Tarbet, Kintyre.
