[1] Before the 14th century the Berwari region, sometimes called Julmar (probably after the town of Julamerk) or Beth Tannura (the name of a large Jewish village in the Beduh valley) in Syriac colophons, was part of the diocese of Dasen.
Nothing is known of the region's history in the 14th and 15th centuries, but a diocese of Berwari is mentioned in a manuscript of 1514 by the scribe Sabrishoʿ bar Galalin, 'brother of the bishop Yahballaha of Julmar'.
In 1731 a manuscript was commissioned from Alqosh by bishop Yahballaha, Therefore, suggesting that he was possibly dependent on the Mosul patriarch Eliya XII.
A petition in 1868 to the Archbishop of Canterbury was signed by Yonan 'of ʿAqri' and Ishoʿyahb 'of Dure', and all three men were mentioned by the Anglican missionary Edward Cutts in 1877.
The consecration of a 'boy of slight education' offended the Anglican Mission, which was trying to persuade the young patriarch to reform the clergy and episcopate, but it did not protest.
Yalda Yahballaha was one of the few surviving members of the Qudshanis hierarchy after the First World War, and remained bishop of Berwari until his death in 1950.
It has been theorized that his young death was due to assassination as a result of the role he played in the Kurdish wars against the Iraqi government.
Timothaus Shallita Yahballaha ended up joining the Syriac Orthodox Church as a result, and was consecrated Archbishop by Patriarch Ignatius Yaqub III on October 23, 1958, in Beirut.
