Lombardy was soon brought to order, and the rebellious nobles banished to Germany. As Otto approached Rome, the people restored the Pope he had appointed, whom they had in the meantime deposed: they were also compelled to give up the leaders of the revolt, who were tried and executed. Otto claimed the right of appointing the Civil Governor of Rome, who should rule in his name. He gave back to the Pope the territory which the latter had received from Pippin the Short, two hundred years before, but nearly all of which had been taken from the Church by the Lombards. In return, the Pope agreed to govern this territory as a part, or province, of the Empire, and to crown Otto's son as Emperor, in advance of his accession to the throne. [Sidenote: 966.] These new successes seem to have quite turned Otto's mind from the duty he owed to the German people; henceforth he only strove to increase the power and splendor of his house. His next step was to demand the hand of the Princess Theophania, a daughter of one of the Byzantine Emperors, for his son Otto. The Eastern Court neither consented nor refused; ambassadors were sent back and forth until the Emperor became weary of the delay. Following the suggestion of his offended pride, he undertook a campaign against Southern Italy, parts of which still acknowledged the Byzantine rule. The war lasted for several years, without any positive result; but the hand of Theophania was finally promised to young Otto, and she reached Rome in the beginning of the year 972. Her beauty, grace and intelligence at once won the hearts of Otto's followers, who had been up to that time opposed to the marriage. Although her betrothed husband was only seventeen, and she was a year younger, the nuptials were celebrated in April, and the Emperor then immediately returned to Germany with his Court and army.
