Diocese of Kashkar

Diocese of Kashkar, sometimes called Kaskar, was the senior diocese in the Church of the East's Province of the Patriarch. It see was in the city of Kashkar. The diocese is attested between the fourth and the twelfth centuries. The bishops of Kashkar had the privilege of guarding the patriarchal throne during the interregnum between the death of a patriarch and the appointment of his successor. As a result, they are often mentioned by name in the standard histories of the Nestorian patriarchs, so that a relatively full list of the bishops of the diocese has survived.
