The Holy Roman Empire is typically said to have been founded by Charlemagne. Otto I is also important in the history of the Empire. He is generally credited with reviving the Empire more than a century after Charlemagne. It is important to note, however, that neither man ever actually used the term “Holy Roman Empire. This term would not come into use until the 1200s. Historians usually say that the Holy Roman Empire, by whatever name, traces its roots to 800 AD, when Charlemagne was crowned emperor by the pope. This began a tradition that held that there was an empire that was the successor to the Roman Empire and whose emperor could only be crowned by the pope.
