[1] As a result of these efforts, Otranto was taken from the Saracens in 873, and Bari, captured from Arabs by the Holy Roman Emperor Louis II in 871, passed under Byzantine control in 876.
[4] In c. 965, a new theme of Lucania was established, and the stratēgos (military governor) of Bari was raised to the title of katepanō of Italy, usually with the rank of patrikios.
From 1016 to 1030 the Normans were pure mercenaries, serving either Byzantine or Lombard, and then Duke Sergius IV of Naples, by installing their leader Ranulf Drengot in the fortress of Aversa in 1030.
[5][6] The title Catapan of Apulia and Campania was revived briefly in 1166 for Gilbert, Count of Gravina, the cousin of the queen regent Margaret of Navarre.
In 1167, with his authority as catapan, Gilbert forced German troops out of the Campania and compelled Frederick Barbarossa to raise the siege of Ancona.
