Intermittent Bulgarian uprisings continued to occur, often with the support of the Serbian princedoms to the north. Any temporary independence that might have been gained was usually crushed swiftly by the Byzantines. It was also marked by periods of war between the Normans and Byzantium. The Normans launched offensives from their lands acquired in southern Italy, and temporarily gained rule over small areas in the northwestern coast.
