In politics, the presence of a Roman Emperor was felt to be desirable long after the empire fell. This tendency reached its peak when Charlemagne was crowned "Roman Emperor" in the year 800, an act which led to the formation of the Holy Roman Empire. The notion that an emperor is a monarch who outranks a mere king dates from this period. In this political ideal, there would always be a Roman Empire, a state whose jurisdiction extended to the entire civilized western world.
