Having put down the rebellion in Seleucia, the Jewish robber brothers
Anilai and
Asinai set about strengthening their hold on Babylonia and training a proper military force. Numbers were very quickly buoyed by their fellow countrymen; the promise of an autonomous Jewish land away from the stringent rule of Rome was enough to levy them substantial recruits among the Mesopotamian Jewish communities. The brothers celebrated their newfound positions of power by making advantageous marriages. Anilai, who was in all things chief, married a converted noble lady,
Iscah of Adiabene, who was a relation to the royal family thereof, whilst Asinai married the woman
Yuwanna, daughter of
Moshe bar Ysu, a Jew from Palmyra who they set up as their High priest.
To their north, neither
Phraates IV and
Artabanus had engaged each other or
Kamnaskires the Elamite. The Parthian Empire was enveloped in civil war, and yet, no blood was being shed. It seemed as if all were reluctant to engage in those conflicts which they knew would be decisive; perhaps if they waited events would overcome at least one or other contender and facilitate the path of the victor, whomever he may be.
Undeterred by this uneasy stalemate, the brothers sent word to Kamnaskires of Elam (Elymais), proposing an alliance. They offered him greater autonomy, even outright independence for his kingdom, in return for his support against their mutual enemies. Let them make a common cause, and be united in marriage, and each establish his own Kingdom out of the Parthian carcass. Kamnaskires jumped at the opportunity; their combined armies stood a far better chance of success than individually. Whilst Kamnaskires had custody of the legitimate prince,
Rhodaspes, the brothers had the administrative capital Ctesiphon and the would-be royal heiress,
Sayarsis; together they would be better able to oust Phraates and come to terms with Artabanus.
In grand style, Anilai and Asinai proceeded to the recently taken Susa. There the alliance was ratified, and the prince Rhodaspes reunited with Sayarsis, whose other nominal husband (and nephew) Mithridates the Mede was left behind under heavy watch in Ctesiphon. As part of the alliance, Kamnaskires married their sister
Mariame, in preparation for which he and all the men of his household were circumsised after paying homage to Adonai, the God of the Jewish people.
The following day, as the princes of the Elamites recovered in their beds, Anilai, Asinai and their bodyguard fell upon them, slaughtering Kamnaskires and all others they were able to come upon - including his sons, wives, concubines and other princes. The other Elamites in attendance were taken captive but promised mercy in return for their cooperation, which they willingly gave. Fearing reprisals from the common populace, they withdrew quickly from the city and sought refuge outside its walls.
Asinai & Anilai attack Susa
Their army was already positioned and quickly descended into Elymais having received affirmative response from Susa. Asinai and Anilai's act of cruelty incited little, if none, public outcry, and Susa was easily taken. Hostages were taken from among all of the nobles, but they otherwise conducted themselves benevolently. A son of Kamnaskires, by name Onnoskapes, took the throne, with Mariame as wife and regent.
Now in control of Assyria (Adiabene), Babylonia and Elymais, Anilai and Asinai had no time to rest. Having been restored to his throne in Antropatene, the
King Darius of Media Antropatene now marched against them, in name of his young son, the would-be
Mithridates IV, who they still had in their power. They were soon informed of the league formed between Darius and Artabanus; the two conspired to divide Phraates' kingdom between them, with Darius expanding into Mesopotamia and Media, and Artabanus taking Hyrcania, Persia and all of the other eastern provinces. At last the time had come for Parthia to be bathed in blood.
