• C. March 15, 900 A.D.

Answer: (A)

The moment historians typically point to as the start of the Holy Roman Empire is Charlemagne’s coronation as emperor on December 25, 800 AD. When the pope crowned Charlemagne, the western Christian successor to the Roman imperial tradition was officially established, creating a new empire that styled itself a continuation of Rome’s legacy in western Europe. This event gave the empire its imperial legitimacy, set up medieval institutions, and linked Charlemagne’s realm to the idea of a revived Roman Empire under a Christian ruler. The other dates don’t correspond to that foundational moment—the first date is far earlier in world history, and the later dates refer to different events or periods within the empire’s long medieval history. While some scholars point to later milestones (like Otto I’s accumulation of power in 962) as a formal or enduring start, the date most often used in educational contexts for the empire’s beginning is the coronation in 800 AD.
