Ashushur-bêlshunu Orotonid

Ashushur-bêlshunu Orotonid (died 277 BC) was semi-autonomous ruler of the Seleukid satrapy of Adiabene. His choice to join the Syrian Rebellion was instrumental in triggering the eastern uprising during the rebellion. He nearly captured the Seleukid capital of Seleukeia Megale, but was prevented from doing so by a mercenary force under Chairondas Onomastig. His opportunity to take the capital lost, and his own capital captured by Antiochos I, he turned north to join up with Datames I. However before that could happen Datames was defeated by Umamaita Chosroid, while he was caught by the mercenaries under Chairondas at Herakleia and himself defeated. His defeat ended the most critical phase of the rebellion, allowing Antiochos to secure his hold on the Seleukid heartlands and slowly subdue the rebellion in the outlying province. Though it would be until 272 BC for the rebellion to be fully subdued with the capture of Demodamas Demodamid.
