Boniface subdued Pavia and Parma, in revolt against the emperor, and the emperor made a treaty with Boniface, an act which has been construed as recognition of Boniface's independence. In 1032, he was at war with the rebel Count Odo II of Blois. In early summer 1036, Boniface attended the emperor at Nijmegen. In 1037, he helped put down a revolt against the Emperor Conrad, and in February 1038, hosted the Emperor, while the latter journeyed to Florence. In 1043, for services rendered the Empire, he received the Duchy of Spoleto and Camerino. He also acquired more land in Parma and Piacenza, and his chief residence in this time was at Mantua.
