The Saracens and the complications in Southern Italy have for a time diverted our attention from the events originating in the altered relations between the city and the Empire. These relations had, however, added to the difficulties in which Rome already found herself. Lambert, reinstated in the Duchy of Spoleto, in the hope of advancing his own aims towards independence and increased authority, had done all in his power to aggravate the disorder which prevailed in Italy. Rome had already felt his hand. The nobles condemned by John had sought refuge with Lambert, and, after the manner of fugitives, had assailed him with entreaties for their restoration. Suspicion sown between the Emperor and the Pope found nourishment in the aims of the sons of Lewis the German, who on their side were eager to gain possession of Italy. Even the friendly relations which existed between Rome and the Greek Emperor, whose generals had again appeared frequently victorious in Southern Italy, further strengthened Charles's distrust, while the consciousness of his own weakness increased his suspicion. He had given the Romans sufficient ground to lament their choice of Emperor, and to wish for another ruler in his place. Charles's correspondence with John is not forthcoming, but a letter of the Pope's throws light on the transaction.
