Carloman of Bavaria was the eldest grandson of what descendant of Charlemagne?
Carloman of Bavaria Carloman (German: "Karlmann" , Latin: "Karlomannus" ; 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 was appointed by King Louis II of Italy as his successor, but the Kingdom of Italy was taken by his uncle Charles the Bald in 875. Carloman only conquered it in 877. In 879 he was incapacitated, perhaps by a stroke, and abdicated Bavaria to Louis the Younger and Italy to Charles the Fat.
Middle Francia Middle Francia (Latin: "Francia media" ) was a short-lived Frankish kingdom which was created in 843 by the Treaty of Verdun after an intermittent civil war between the grandsons of Charlemagne resulted in division of the united empire. Middle Francia was allocated to emperor Lothair I, the eldest son and successor of emperor Louis the Pious. His realm contained the imperial cities of Aachen, the residence of Charlemagne, as well as Pavia but lacked any geographic or ethnic cohesion which prevented it from surviving and forming a nucleus of a larger state, as was the case with West Francia and East Francia.
