Before David I became the King of Scotland in 1124, he was the prince of the Cumbrians and earl of a great territory in the middle of England acquired by marriage. This period marks the beginning of his life as a great territorial lord. Circa 1113, the year in which King Henry I of England arranged his marriage to an English heiress and the year in which for the first time David can be found in possession of "Scottish" territory, marks the beginning of his rise to Scottish leadership.
