Abbasids
Ercolian Jews were very open minded and ecumenical Jews from Ercolia. After the execution of Haninai in 591, a Ma'amad governed the Ercolian Jews. They were joined by Romaniotes evicted by Phocas.
The Ercolian Jews served in Khosrau II's army but after defeating the Romans in 610, Khosrou II did not allow them to settle in the Patriarchate of Jerusalem so they settled in Edessa where they took Bayah from the Judeo-Baptist Gnostic Gabriel of Tachkastan who was the author of a Noahite movement among the Gentile-Gnostic Parthians of Tachkastan.
When Emperor Heraclius evicted the Ercolian Jews from Edessa in the early 620s, Heraclius permitted them to keep Arabia if they could conquer it and unite its people in Miaphysitism. The Ercolian Jews went to Tachkastan where they admitted Gabriel's student ibn-Ishmael into the Ma'amad and tried to raise a Noahite Army from among the Parthians and Arabs to carry out the command of Heraclius.
Under the leadership of Ma'amad the Ercolian Jews and their Parthian/Arab army conquered the Sassanians and the Patriarchate of Jerusalem.
Eventually an Arab convert to Judeo-Baptist Gnosticism called Uthman became the leader of the community and had the Judeo-Baptist Gnostic writings translated into the Imperial dialect of Cyrus for his people.
