Abstract: This study attempts to provide a new framework for ninth-century Irish and Scottish history. Viking Scotland, known as Lothlend, Laithlinn, Lochlainn and comprising the Northern and Western Isles and parts of the mainland, especially Caithness, Sutherland and Inverness, was settled by Norwegian Vikings in the early ninth century. By the mid-century it was ruled by an effective royal dynasty that was not connected to Norwegian Vestfold. In the second half of the century it made Dublin its headquarters, engaged in warfare with Irish kings, controlled most Viking activity in Ireland, and imposed its overlordship and its tribute on Pictland and Strathclyde. When expelled from Dublin in 902 it returned to Scotland and from there it conquered York and re-founded the kingdom of Dublin in 917.
