Noahite Christian Gnostic
The Taji (tʾcyk') of Tachkastan were a sect of Essenes (Judeo-Baptist Gnostics) from the Formerly Roman Province of Tachkastan which was conquered by the Persians in 610AD. The Manicheans had seceded from them under the influence of Marcionism and Mandaeism.
They spoke Achamenid Arabic.
610
After defeating the Romans in 610, the Ercolian Karaites who had settled in Mamuca did not allow the Taji access to Al-Masjid Al-Haram in Jerusalem.
620s
Gabriel of the Taji came from Heraclius announcing the decree from on high to unite in religion. They were supported by various Pahlavi families. The Ercolian Karaites thought they could use this to their advantage and went from Edessa to Tachkastan where their Ma'amad, Mehmet, Muhmad, Mahmud established an alliance with the Taji in 622.
636
The Taji made an alliance with Al-Lahazim in 636 through Shahrbonu and converted Uthman of the Ercolian Karaites to their religion.
644
Uthman came to power and promoted the Quran much to the annoyance of his family and other Ercolian Karaites.
656
Uthman appointed Ali as his successor. The Ercolian Karaites went to war against the Taji & Al-Lahazim but the Taji & Al-Lahazim won.
660
The Taji ruled until 660 when they were overthrown by the Ercolian Karaites again. The terms of the peace treaty promised that the Taji & Al-Lahazim Candidate (Hussein) would rule following Muawiya.
680
The Ercolian Karaites did not keep their promise and killed the Taji & Al-Lahazim Candidate. Hence the Al-Lahazim established ibn Al-Zubayir as their ruler while the Taji fled first to Armenia then Thrace.
The Taji still survive today as the Tzigane of Biharia.
