Alexander I of Scotland
On the death of Edgar in 1107, Alexander succeeded to the Scottish crown but, in accordance with Edgar's instructions, their brother David was granted an appanage in southern Scotland. Edgar's will granted David the lands of the former kingdom of Strathclyde or Cumbria, and this was apparently agreed in advance by Edgar, Alexander, David and their brother-in-law Henry I of England. In 1113, perhaps at Henry's instigation, and with the support of his Anglo-Norman allies, David demanded and received, additional lands in Lothian along the Upper Tweed and Teviot. David did not receive the title of king, but of "prince of the Cumbrians", and his lands remained under Alexander's final authority.
