Artabanus II (also spelled Artabanos II or Ardawan II; Ardawān), incorrectly known in older scholarship as Artabanus III, was King of Kings of the Parthian Empire from 12 to 38/41 AD, with a one-year interruption. He was the nephew and successor of Vonones I (). His father was a Dahae prince, whilst his mother was a daughter of the Parthian King of Kings Phraates IV () Before his ascension to the Parthian crown, Artabanus had ruled as king of Media Atropatene, which later served as his base of attacks against the Roman-supported Parthian king Vonones I. Artabanus eventually defeated Vonones I, who fled to Armenia and became its king. Artabanus' efforts to replace Vonones I with his son were blocked by the Romans, who eventually reached an agreement with the Parthians to appoint Artaxias III the new king of Armenia and renounce their support of Vonones I. Name is the Latin form of the Greek Artábanos (), itself from the Old Persian *Arta-bānu ("the glory of Arta."). The Parthian and Middle Persian variant was Ardawān (). Background and kingship of Media Atropatene Artabanus was not from the ruling branch of the Arsacid royal family; his father was a Dahae prince, who was most likely descended from the former Parthian monarch Mithridates II (), whilst his mother was a daughter of the incumbent Parthian King of Kings Phraates IV (). Born between 30–25 BC, Artabanus was raised amongst the Dahae in Central Asia. When he reached adulthood, he became the ruler of Media Atropatene, which occurred sometime during the late reign of Phraates IV or during the reign of the latters son and successor Phraates V (). The factor behind Artabanus' rise to kingship of Media Atropatene is unclear. The kingdom served as Artabanus' headquarters of his attacks against the Parthian king Vonones I ( AD), with whom he fought against over the crown. Vonones I, who had originally resided in Rome, had been placed on the Parthian throne by a faction led by the Karin and Suren clans. His rule was supported by the Romans. However, the Parthian nobility was quickly alienated by Vonones I, who had become Romanized during his stay in Rome. This increased Artabanus' odds—after years of fighting—to finally defeat Vonones I, who fled to Armenia and became its king.
