In 1792 or 1793 a separate Syrian Orthodox diocese was created for Mosul, hitherto under the jurisdiction of the diocese of Mar Mattai, in response to the consecration of a Syrian Catholic bishop for Mosul in 1790 [REF].
In the 1840s, shortly after it recovered the ancient monastery of Mar Awgin from the East Syrians, the Syrian Orthodox church revived the old diocese of Nisibis.
