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.
Kingdom of Germany The Kingdom of Germany or German Kingdom (Latin: "Regnum Teutonicum" , "Teutonic Kingdom"; German: "Deutsches Reich" ) developed out of the eastern half of the former Carolingian Empire. Like Anglo-Saxon England and medieval France, it began as "a conglomerate, an assemblage of a number of once separate and independent... "gentes" [peoples] and "regna" [kingdoms]." East Francia ("Ostfrankenreich") was formed by the Treaty of Verdun in 843, and was ruled by the Carolingian dynasty until 911, after which the kingship was elective. The initial electors were the rulers of the stem duchies, who generally chose one of their own. After 962, when Otto I was crowned emperor, the kingdom formed the bulk of the Holy Roman Empire, which also included Italy (after 951), Bohemia (after 1004) and Burgundy (after 1032).
