Under Tigranes, Armenia ascended to a pinnacle of power unique in its history and became, albeit briefly, the strongest state in the Roman east. Extensive territories were taken from the kingdom of Parthia in Iran, which was compelled to sign a treaty of alliance. Iberia (Georgia), Albania, and Atropatene had already accepted Tigranes’ suzerainty when the Syrians, tired of anarchy, offered him their crown (83 BCE). Tigranes penetrated as far south as Ptolemais (modern ʿAkko, Israel).
