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).
