"Lords of the Isles" refers to a title held by the rulers of the Isle of Man and the Hebrides in Scotland during the medieval period. These lords controlled significant maritime territories and were influential in the politics and trade of the region. Their power peaked in the 13th century, when they governed a vast area that included various islands and coastal lands. The title was often associated with the MacDonald clan, who played a crucial role in the history of the Western Isles. The lords faced challenges from both the Scottish crown and rival clans, leading to conflicts that shaped the region's history. The title eventually diminished in power, particularly after the Battle of Bannockburn in 1314.
