In contrast to most of Scotland, the north-western coast and the islands beyond were a region of mixed political control as well as culture into the sixteenth century. The divergent influences of Celtic and Scandinavian culture were more marked here than in the evolving mainland kingdom of Scots. It was a physically remote region of substantial autonomy under its own dynasties. Timothy Venning explores the whole of the lordship of the Isles at its widest extent, under Somerled MacGillebride (ruled c. 1130-64), encompassing the kingdom of Man during its independent history, plus the mainland domains of Somerled's family in the western Highlands. He also covers the jarldom of Orkney, a Scandinavian lordship divided between involvement in and allegiance to Scotland and Norway until the later fifteenth century.
