David I of Scotland was a 12th-century monarch who ruled Scotland from 1124 until his death in 1153. Born around 1084 to King Malcolm III and Queen Margaret, he spent much of his youth in England under the influence of Henry I. Before ascending the throne, he served as the Prince of the Cumbrians. His reign was characterized by significant structural changes to the Scottish state, including the introduction of feudalism and the establishment of various burghs and monasteries.
