Step-by-step explanation:
The Holy Roman Empire was a regional state that ruled Germany and occasionally sought to wield influence in eastern Europe and Italy.
Charlemagne, who founded the Holy Roman Empire in 800, established four main entities: the Kingdom of Italy, the Kingdom of Germany, the Kingdom of Burgundy, and the Kingdom of Bohemia. Each of these kingdoms comprised a loose coalition of independent territories with different hereditary rulers.
The Holy Roman Empire remained a weak and decentralized political entity, consisting of over one hundred principalities with varying degrees of power and autonomy. The emperor was elected by a handful of rulers known as electors and was also beholden to the pope.
