921-954. King of France from 936. His reign was marked by the rebellion of nobles who refused to recognize his authority. As a result of his liberality they were able to build powerful feudal lordships. He was raised in England after his father Charles III, the Simple, had been overthrown 922 by Robert I. After the death of Raoul, Robert's brother-in-law and successor, Louis was chosen by the nobles to be king. He had difficulties with his vassal Hugh the Great, and skirmishes with the Hungarians, who had invaded S France.
