The next year, Lothair III came down to Rome for his imperial coronation. The rebel leaders met him there, but they were refused help because Lothair's force was too small. With the emperor's departure, divisions in his opponents' ranks allowed Roger to reverse his fortunes. By July 1134, Roger's troops had forced Ranulf, Sergius, and the other ringleaders to submit. Robert was expelled from Capua and Roger installed his third son, Alfonso of Hauteville as Prince of Capua. Roger II's eldest son Roger was given the title of Duke of Apulia.
