List of maphrians

The Maphrian, originally known as the Grand Metropolitan of the East and also known as the Catholicos, was the head of the Syriac Orthodox Church in Sassanid Persia, and was the second highest-ranking prelate within the Syriac Orthodox Church, after the Patriarch of Antioch. Following the Chalcedonian schism, the Sassanian Church split into two separate churches after the ordination of Ahudemmeh as Grand Metropolitan of the East by Jacob Baradaeus in 559 due to christological differences. The miaphysite church organised by Ahudemmeh went on to form what was later named the Maphrianate of the East, whilst the traditional dyophysite East Syriac Church is known simply as the Church of the East.
The title of maphrian was first used to refer to John IV Saliba, and was likely adopted in c. 1100. A separate Maphrianate of Tur Abdin under the authority of the Patriarch of Tur Abdin was established in c. 1479, which endured until 1844, and eventually the Maphrianate of the East was abolished in 1860. A maphrianate in India was established in 1912, thereby creating the Malankara Orthodox Syrian Church, but was not recognised by the Syriac Orthodox Church until 1958. In 1975, Patriarch Ignatius Jacob III withdrew recognition of the maphrian Baselios Augen I, and appointed Baselios Paulose II as his successor. The Malankara Orthodox Syrian Church thus split from the Jacobite Syrian Christian Church, which remained part of the Syriac Orthodox Church.
