Carloman, or in German Karlmann (c. 830 ? 22 March 880), was a Frankish king of the Carolingian dynasty. He was the eldest son of Louis the German, king of East Francia, and Hemma, daughter of a Bavarian count. His father appointed him margrave of Pannonia in 856, and upon his father's death in 876 he became King of Bavaria. He claimed the Kingdom of Italy from 875, but only conquered it in 877. In 879 he was incapacitated, perhaps by a stroke. On his death his kingdoms passed to his younger brothers: Bavaria to Louis the Younger and Italy to Charles the Fat (wikipedia)
