Charlemagne was crowned “emperor of the Romans” by Pope Leo III in 800 CE, thus restoring the Roman Empire in the West for the first time since its dissolution in the 5th century. Charlemagne was selected for a variety of reasons, not least of which was his long-standing protectorate over the papacy. His protector status became explicit in 799, when the pope was attacked in Rome and fled to Charlemagne for asylum. The ensuing negotiations ended with Leo’s reinstallation as pope and Charlemagne’s own coronation as Holy Roman emperor.
