Louis I, Le Debonnaire or Gentle, Roman Emperor, 814-840, was born 778, and was son of Charlemagne by his wife Hildegarde. He married Lady Judith, the Fair Maid of Bavaria, and by her had a son who succeded him, Charles II, King of France. He had succeeded his father in 814, but in 817 he yielded to the wishes of his sons and gave each of them a share of his dominions, and thus complications arose from which resulted the dissolution of the Empire. He died 840. By his first wife, Irmingardis, daughter of Ingram, Count of Hasbania in Saxony, he had a daughter Alpaidia.
