The Jewish Exilarch Haninai ruled from 580 to 590-591 when (according to Karaite sources) he was put to death by Khosrau II for supporting the Pahlavi Bahram VI. The next Exilarch's name appears to have been Gabirol. Jews were used as soldiers by Khosrau and were led by a [http://www.jewishencyclopedia.com/articles/10222-ma-amad Mahamad] but after Khosrau's attempt to eradicate the Exilarchs, the Jewish government would eventually attempt to secure themselves in Edessa leaving the Jews with no public Exilarch again until Bostenai was installed by Umar following Umar's massacre of the Jews of Arabia.

===602 Al-Hira===Ignorant Iyas ibn Qabisah al-Taji He is appointed governor of Al-Hira under Nakhiragan. A. J. Deus proposed that he is the historical person behind prophet Muhammad. This is the second time that Iyas is given authority by Khosrau. Although ignorant at this time it is very likely that he would have made every effort to get an education while in power this second time around so as not to lose power again. However, little did he know that his ignorance was the only reason the Sassanians put him in his position.
===604 "Gregory"===
When the Catholicos Gregorius died a few years later in 608, the bishops made the usual request to the king to allow them to elect a new Catholicos, but Khosrau II had not forgotten the events of the previous election and refused them leave to do so. The royal physician Gabriel of Shiggar, a staunch Monophysite, used his influence with the king to prevent an election while suggesting Khosrau make Henana of Adiabene or one of his students Catholics but Khosrau's mind was made up.
The Acephalian Gnostic Pahlavis are keen to convert the suddenly Acephali Dyophysites to increase the Acephali faction and build up their party for a coup against Khosrau.
