Artabanus

Artabanus ( Artabanos; Ardawān) may refer to various rulers/monarchs of ancient Persia and Parthia: Artabanus (son of Hystaspes), brother of Darius I and uncle of Xerxes I Artabanus of Persia, Hyrcanian by birth, commander of Xerxes's guard, and Xerxes's assassin (465 BC) Artapanus (general), general under Xerxes I (486–465 BC) Artabanus I of Parthia, c. 127–124 BC Artabanus II of Parthia, c. 12 to 38/41 AD Artabanus III of Parthia, 79/80 – 81 Artabanus IV of Parthia, c. 213 to 224 Artabanus of Khwarazm, c.1st-2nd century AD

Confusingly, two systems exist for the regnal numbers of the Artabanuses; in older works, they may be numbered as a regnal number higher than listed above; i.e. Artabanus IV might refer to Artabanus III.
