"Yet more than to the eastern forests from which his forbears had come, Charlemagne's spirit was drawn to the Roman south. He saw himself as the head of Christendom and its guardian. Like his father, Pepin, he led a Frankish army across the Alps against the Lombard conquerors of north Italy. And on Christmas day 800, as he knelt at mass in St. Peter's, Rome, his ally the pope crowned him with traditional imperial rites as Augustus and emperor of the Romans. To dreamers it appeared as if the hand of time had been set back and the Roman Empire was restored. And it was now, it seemed, a Holy Roman Empire."
