The Metropolitanate of Merv was an East Syriac metropolitan province of the Church of the East, between the fifth and eleventh centuries, with several known suffragan dioceses.
At least one East Syriac diocese in Khorasan existed by the beginning of the fifth century, though it was not assigned to a metropolitan province in 410. After establishing five metropolitan provinces in Mesopotamia, Canon XXI of the synod of Isaac provided that 'the bishops of the more remote dioceses of Fars, of the Islands, of Beth Madaye, of Beth Raziqaye and of the country of Abrashahr must accept the definition established in this council at a later date'. By implication, Abrashahr (Nishapur) already had a bishop at this period. [1]
Four East Syriac dioceses in Khorasan and Segestan are attested a few years later. The bishops Bar Shaba of Merv, David of Abrashahr, Yazdoï of Herat and Aphrid of Segestan were present at the synod of Dadishoʿ in 424. [2] The uncommon name of the bishop of Merv, Bar Shaba, means 'son of the deportation', suggesting that Merv's Christian community may have been deported from Roman territory.
The diocese of Segestan, whose bishop probably sat at Zarang, was disputed during the schism of Narsaï and Elishaʿ in the 520s. The patriarch Aba I resolved the dispute in 544 by temporarily dividing the diocese, assigning Zarang, Farah and Qash to the bishop Yazdaphrid and Bist and Rukut to the bishop Sargis. He ordered that the diocese should be reunited as soon as one of these bishops died. [3]
The Christian population of the Merv region seems to have increased during the sixth century, as the bishop of Merv was recognised as a metropolitan at the synod of Joseph in 554 and Herat also became a metropolitan diocese shortly afterwards. The first known metropolitan of Herat was present at the synod of Ishoʿyahb I in 585. The growing importance of the Merv region for the Church of the East is also attested by the appearance of several more Christian centres during the late fifth and sixth century. By the end of the fifth century the diocese of Abrashahr (Nishapur) also included the city of Tus, whose name featured in 497 in the title of the bishop Yohannis of 'Tus and Abrashahr'. Four more dioceses seem also to have been created in the sixth century. The bishops Yohannan of 'Abiward and Shahr Peroz' and Theodore of Merw-i Rud accepted the acts of the synod of Joseph in 554, the latter by letter, while the bishops Habib of Pusang and Gabriel of 'Badisi and Qadistan' adhered by proxy to the decisions of the synod of Ishoʿyahb I in 585, sending deacons to represent them. [4] None of these four dioceses is mentioned again, and it is not clear when they lapsed.
Timothy I consecrated a metropolitan named Hnanishoʿ for Sarbaz in the 790s. This diocese is not mentioned again. In 893 Eliya of Damascus listed both Merv and Herat as metropolitan provinces. Segestan was a suffragan diocese of Herat, while Merv had suffragan dioceses for 'Dair Hans', 'Damadut', and 'Daʿbar Sanaï', three districts whose locations are entirely unknown. [5]
By the eleventh century East Syriac Christianity was in decline in Khorasan and Segestan. The last-known metropolitan of Merv was ʿAbdishoʿ, who was consecrated by the patriarch Mari (987–99). The last-known metropolitan of Herat was Giwargis, who flourished in the reign of Sabrishoʿ III (1064–72). If any of the suffragan dioceses were still in existence at this period, they are not mentioned. The surviving urban Christian communities in Khorasan suffered a heavy blow at the start of the thirteenth century, when the cities of Merv, Nishapur and Herat were stormed by Genghis Khan in 1220. Their inhabitants were massacred, and although all three cities were refounded shortly afterwards, it is likely that they had only small East Syriac communities thereafter. Nevertheless, at least one diocese survived into the thirteenth century. In 1279 an unnamed bishop of Tus entertained the monks Bar Sawma and Marqos in the monastery of Mar Sehyon near Tus during their pilgrimage from China to Jerusalem.
The bishop Barshabba ('son of the deportation') of Merv was among the signatories of the acts of the synod of Dadishoʿ in 424. [6]
The bishop 'Pharumai', 'bishop of the town of Merv', was among the signatories of the acts of the synod of Acacius in 486. [7]
The bishop Yohannan of Merv was among the signatories of the acts of the synod of Babaï in 497. [8]

The metropolitan ʿAbdishoʿ, formerly bishop of Ispahan, was appointed metropolitan of Merv by the patriarch Mari (987–99). [12] He was metropolitan of Merv when Elijah of Nisibis completed his Chronography in 1018/19. [13]
The bishop Yazdoï of Herat was among the signatories of the acts of the synod of Dadishoʿ in 424. [14]

The priest Daniel was among the signatories of the acts of the synod of Ishoʿyahb I in 585, on behalf of the metropolitan Gabriel of Herat. [16]
The metropolitan Aristus of Herat was degraded during the patriarchate of Sliba-zkha (714–28) and replaced by Yohannan, who was himself degraded during the patriarchate of Pethion (731–40) and replaced by Panahishoʿ. [17]
The bishop Aphrid of Segestan was among the signatories of the acts of the synod of Dadishoʿ in 424. [18]
In 540 the diocese of Segestan was disputed between two bishops, Yazdaphrid and Sargis, consecrated during the schism of Narsaï and Elishaʿ. The patriarch Mar Aba I, after taking evidence for both parties, resolved the dispute by temporarily dividing the diocese, placing Yazdaphrid in charge of 'the church of the Christians of Zarang, Farah and Qash' and Sargis over the churches of Bist and Rukut. He insisted that the diocese should be reunited after the death of one or other bishop. [19]
The bishop Kurmah of Segestan was among the signatories of the acts of the synod of Ezekiel in 576. [20]
The patriarch Sabrishoʿ III consecrated Giwargis of Kashkar a bishop shortly after his consecration in 1063/4 'and sent him to Khorasan and Segestan'. Giwargis then 'travelled on to the territory of the Khitan (al-Khita), where he remained until the end of his life'. [21]
The bishop David of Abrashahr was among the signatories of the acts of the synod of Dadishoʿ in 424. [22]
The bishop Yohannis of Tus and Abrashahr was among the signatories of the acts of the synod of Babaï in 497. [23]

At the height of its power, in the 10th century AD, the dioceses of the Church of the East numbered well over a hundred and stretched from Egypt to China. These dioceses were organised into six interior provinces in Mesopotamia, in the Church's Iraqi heartland, and a dozen or more second-rank exterior provinces. Most of the exterior provinces were located in Iran, Central Asia, India and China, testifying to the Church's remarkable eastern expansion in the Middle Ages. A number of East Syriac dioceses were also established in the towns of the eastern Mediterranean, in Palestine, Syria, Cilicia and Egypt.
The Metropolitanate of Maishan or Maysan was an East Syriac metropolitan province of the Church of the East between the fifth and thirteenth centuries. The historical region of Maishan or Maysan is situated in southern Iran. The metropolitans of Maishan sat at Prath d'Maishan, and for most of its history the province had three suffragan dioceses, at Karka d'Maishan, Rima and Nahargur. The last metropolitan of Maishan, the noted East Syriac author Shlemun (Solomon) of Basra, is attested in 1222, and it is not clear when the province ceased to exist.
Metropolitanate of Beth Garmai was an East Syriac metropolitan province of the Church of the East between the fifth and fourteenth centuries. The region of Beth Garmai is situated in northern Iraq, bounded by the Little Zab and Diyala Rivers and centered on the town of Karka d'Beth Slokh. Several bishops and metropolitans of Beth Garmaï are mentioned between the fourth and fourteenth centuries, residing first at Shahrgard, then at Karka d'Beth Slokh, later at Shahrzur and finally at Daquqa. The known suffragan dioceses of the metropolitan province of Beth Garmaï included Shahrgard, Lashom (ܠܫܘܡ), Khanijar, Mahoze d'Arewan, Radani, Hrbath Glal (ܚܪܒܬܓܠܠ), Tahal and Shahrzur. The suffragan dioceses of 'Darabad' and 'al-Qabba', mentioned respectively by Eliya of Damascus and Mari, are probably to be identified with one or more of these known dioceses. The diocese of Gawkaï, attested in the eighth and ninth centuries, may also have been a suffragan diocese of the province of Beth Garmaï. The last known metropolitan of Beth Garmaï is attested in the thirteenth century, and the last known bishop in 1318, though the historian ʿAmr continued to describe Beth Garmai as a metropolitan province as late as 1348. It is not clear when the province ceased to exist, but the campaigns of Timur Leng between 1390 and 1405 offer a reasonable context.
The Patriarchal Province of Seleucia-Ctesiphon was an ecclesiastical province of the Church of the East, with see in Seleucia-Ctesiphon. It was attested between the fifth and thirteenth centuries. As its name entails, it was the province of the patriarch of the Church of the East. The province consisted of a number of dioceses in the region of Beth Aramaye, between Basra and Kirkuk, which were placed under the patriarch's direct supervision at the synod of Yahballaha I in 420.
The Metropolitanate of Nisibis was an East Syriac metropolitan province of the Church of the East, between the fifth and seventeenth centuries. The ecclesiastical province of Nisibis had a number of suffragan dioceses at different periods in its history, including Arzun, Beth Rahimaï, Beth Qardu, Beth Zabdaï, Qube d’Arzun, Balad, Shigar (Sinjar), Armenia, Beth Tabyathe and the Kartawaye, Harran and Callinicus (Raqqa), Maiperqat, Reshʿaïna, Qarta and Adarma, Qaimar and Hesna d'Kifa. Aoustan d'Arzun and Beth Moksaye were also suffragan dioceses in the fifth century.
Beth Huzaye or ʿIlam was an East Syriac metropolitan province of the Church of the East, between the fifth and fourteenth centuries. The metropolitan bishops of Beth Huzaye sat at Beth Lapat (Jundishapur). The metropolitan province of Beth Huzaye had a number of suffragan dioceses at different periods in its history, including Karka d'Ledan, Hormizd Ardashir, Shushter, Susa, Ispahan, Mihraganqadaq and Ram Hormizd. The Diocese of Shahpur Khwast may also have been a suffragan Diocese of the province of Beth Huzaye.
Metropolitanate of Adiabene was an East Syriac metropolitan province of the Church of the East between the 5th and 14th centuries, with more than fifteen known suffragan dioceses at different periods in its history. Although the name Hadyab normally connoted the region around Erbil and Mosul in present-day Iraq, the boundaries of the East Syriac metropolitan province went well beyond the Erbil and Mosul districts. Its known suffragan dioceses included Beth Bgash and Adarbaigan, well to the east of Adiabene proper.
The Metropolitanate of Hulwan was an East Syriac metropolitan province of the Church of the East between the eighth and twelfth centuries, with suffragan dioceses for Dinawar, Hamadan, Nihawand and al-Kuj. The city of Hulwan was one of the chief towns in the western Iranian province of Media. The metropolitanate of Hulwan was ranked among the 'exterior provinces', so called to distinguish them from the province of the patriarch and the five core Mesopotamian 'interior' provinces.
Metropolitanate of Fars was an East Syriac metropolitan province of the Church of the East between the sixth and twelfth centuries. It was centered in what is now Fars Province, the historic cradle of ancient Persian civilization. Besides several centers in the Fars region itself, this East Syriac ecclesiastical province also included several dioceses in Arabia and a diocese for the island of Soqotra.
The Metropolitanate of Rai was an East Syriac metropolitan province of the Church of the East, between the eighth and twelfth centuries. The province of Rai had a suffragan diocese for Gurgan.
For much of the nineteenth and twentieth centuries the district of Salmas in northwest Iran was an archdiocese of the Chaldean Catholic Church, now a part of the Chaldean Catholic Archeparchy of Urmyā.
Chaldean Catholic Eparchy of Amadiya was a historical eparchy (diocese) of the Chaldean Catholic Church, until it was united with the Chaldean Catholic Eparchy of Zakho in 2013.
Chaldean Catholic Eparchy of Seert was a diocese of the Chaldean Catholic Church, centered in Seert. It existed during the eighteenth, nineteenth and early-twentieth centuries. The diocese was ruined during the First World War.
The Diocese of Amid (Diyarbakir) was a diocese or archdiocese of the Chaldean Church from the sixteenth to the twentieth century.

The Diocese of Tirhan was an East Syriac diocese of the Church of the East, within the central ecclesiastical Province of the Patriarch. The diocese is attested between the sixth and fourteenth centuries.
Diocese of Kashkar, sometimes called Kaskar, was the senior diocese in the Church of the East's Province of the Patriarch. Its 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.
Diocese of Adarbaigan was one of the classical East Syriac dioceses of the Church of the East. The diocese, attested between the fifth and eighth centuries, was centred on the town of Ganzak and was included in the metropolitan province of Adiabene.
Giwargis I was patriarch of the Church of the East from 661 to 680.
Diocese of Armenia was an East Syriac diocese of the Church of the East between the fifth and fourteenth centuries. The diocese served members of the Church of the East in Armenia, and its bishops sat at Halat. The diocese is last mentioned in 1281, and probably lapsed in the fourteenth century during the disorders that attended the fragmentation of the Mongol empire.
Simandu was an archdiocese of the Syriac Orthodox Church in Tzamandos, Cappadocia, attested between the tenth and twelfth centuries. Thirteen of its bishops are mentioned in the lists of Michael the Syriac and other Jacobite sources.
