John of Conza

John of Conza or Compsa, was a native of Compsa. Taking advantage of the turmoil in the Exarchate of Ravenna and the preoccupation of the Byzantine emperor Heraclius with the Persian war in the East, he attacked and captured Naples, becoming its second duke. His rebellion was put down by the exarch of Ravenna, Eleutherius. Consinus and many of his followers were killed in the process.
