CARLOMAN (828-880), king of Bavaria and Italy, was the eldest son of Louis the German, king of the East Franks. He married a daughter of Ernest, count of the Bohemian mark, and in conjunction with his father-in-law resisted the authority of his father in 861. In 865 an arrangement was made by which he became possessed of Bavaria and Carinthia as his expectant share of the kingdom of Louis. During the troubles between Louis and his two younger sons Carloman remained faithful to his father, and carried on the war with the Moravians so suc cessfully that when peace was made at Forchheim in 874 they recognized the Frankish supremacy. In 875 the emperor Louis II. died, having named his cousin Carloman as his successor in Italy. Carloman crossed the Alps to claim his inheritance, but was cajoled into returning by the king of the West Franks, Charles the Bald. In 876, on his father's death, Carloman be came actually king of Bavaria, and after a short campaign against the Moravians he went again to Italy in 877 and was crowned king of the Lombards at Pavia ; but his negotiations with Pope John VIII. for the imperial crown were fruitless. Stricken with paraly sis, he bequeathed the whole of his lands to Louis. He died on Sept. 22, 88o, at Ottingen, where he was buried, leaving an illegitimate son, afterwards the emperor Arnulf.
