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.
Franz, Duke of Bavaria Franz, Duke of Bavaria (German: "Franz Bonaventura Adalbert Maria Herzog von Bayern"; born 14 July 1933) is head of the House of Wittelsbach, the former ruling family of the Kingdom of Bavaria. His great-grandfather King Ludwig III was the last ruling monarch of Bavaria until deposed in 1918.
