Neboulos


Neboulos was a South Slavic or Bulgar military commander in the service of the Byzantine emperor Justinian II, who defected with many of his men to the Arabs during the crucial Battle of Sebastopolis.
In 688/9, Justinian II forcibly transplanted Slavic populations from the Balkans and settled them in the depopulated Opsician Theme. From them, he recruited a special military corps, allegedly 30,000 strong, which was called in Greek λαός περιούσιος, "the chosen people". In about 690, Neboulos, who already held the rank of skribon and possibly served in the imperial guard, was placed as their commander. Neboulos's own origin is disputed between scholars, with some suggesting a Bulgar origin and others a South Slavic one. According to the account of Patriarch Nikephoros, he was chosen from among the nobility of the Slav settlers.
In 692/3, after the corps' training had been completed, they were employed en masse by Justinian II in a major campaign against the Umayyads under the strategos of the Anatolics, Leontios. The Byzantines engaged the Arabs in the Battle of Sebastopolis and initially had the upper hand until Neboulos, with the bulk of his men, deserted the Byzantine lines and went over to the Arabs, allegedly bribed by the Arab commander, Muhammad ibn Marwan. Some sources report, probably with great exaggeration, how thereafter Justinian took his revenge on the remaining Slavs: he disbanded the corps, and killed or sold into slavery many of its men, as well as the families of the deserters. Neboulos and his men, on the other hand, were settled by the Umayyads in Syria, and were employed in subsequent Arab forays into Byzantine-held Asia Minor.
