Patriarchal Province of Seleucia-Ctesiphon

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.

According to Eliya of Damascus, there were thirteen dioceses in the province of the patriarch in 893: Kashkar, al-Tirhan (Tirhan), Dair Hazql (an alternative name for al-Nuʿmaniya, the chief town in the diocese of Zabe), al-Hira (Hirta), al-Anbar (Piroz Shabur), al-Sin (Shenna d'Beth Ramman), ʿUkbara, al-Radhan, Nifr, al-Qasra, 'Ba Daraya and Ba Kusaya' (Beth Daraye), ʿAbdasi (Nahargur) and al-Buwazikh (Konishabur or Beth Waziq).^[1] Eight of these dioceses already existed in the Sassanian period, but the diocese of Beth Waziq is first mentioned in the second half of the seventh century, and the dioceses of ʿUkbara, Radhan, Nifr and Qasr were probably founded in the ninth century. The diocese of Nahargur was in the province of Maishan during the Sassanian period, and it is not known when or why it was transferred to the diocese of the patriarch. The first bishop of ʿUkbara whose name has been recorded, Hakima, was consecrated by the patriarch Sargis around 870, and bishops of Qasr, Radhan and Nifr are first mentioned in the tenth century. A bishop of 'Qasr and Nahrawan' became patriarch in 963, and then consecrated bishops for Radhan and for 'Nifr and Nil'. Eliya's list helps to confirm the impression given by the literary sources, that the East Syrian communities in Beth Aramaye were at their most prosperous in the tenth century.

A partial list of bishops present at the consecration of the patriarch Yohannan IV in 900 included several bishops from the province of the patriarch, including the bishops of Zabe and Beth Daraye and also the bishops Ishoʿzkha of 'the Gubeans', Hnanishoʿ of Delasar, Quriaqos of Meskene and Yohannan 'of the Jews'. The last four dioceses are not mentioned elsewhere and cannot be satisfactorily localised.^[2]

In the eleventh century decline began to set in. The diocese of Hirta (al-Hira) came to an end, and four other dioceses were combined into two: Nifr and al-Nil with Zabe (al-Zawabi and al-Nuʿmaniya), and Beth Waziq (al-Buwazikh) with Shenna d'Beth Ramman (al-Sin). Three more dioceses ceased to exist in the twelfth century. The dioceses of Piroz Shabur (al-Anbar) and Qasr and Nahrawan are last mentioned in 1111, and the senior diocese of Kashkar in 1176. In 1139, at the consecration ceremony of the patriarch ʿAbdishoʿ III, a bishop from the province of Nisibis was required to proclaim the new patriarch's name, 'because all the bishops of the grand eparchy [Beth Aramaye] had died and their thrones were vacant; something which had never happened before'.^[3]

The trend of decline continued in the thirteenth century. The diocese of Zabe and Nil is last mentioned during the reign of Yahballaha II (1190–1222), and the diocese of ʿUkbara in 1222. Only three dioceses are known to have been still in existence at the end of the thirteenth century: Beth Waziq and Shenna, Beth Daron and (perhaps due to its sheltered position between the Tigris and the Jabal Hamrin) Tirhan. However, East Syrian communities may also have persisted in districts which no longer had bishops: a manuscript of 1276 was copied by a monk named Giwargis at the monastery of Mar Yonan 'on the Euphrates, near Piroz Shabur which is Anbar', nearly a century and a half after the last mention of a bishop of Anbar.^[4]

The first bishop of Seleucia-Ctesiphon whose historical existence is not in doubt was Papa bar Aggai, who was consecrated around 280. At a turbulent synod convened at Seleucia-Ctesiphon in 315, Papa secured grudging recognition from the other Persian bishops of the primacy of the diocese of Seleucia-Ctesiphon.^[5]

According to legend, the diocese of Kashkar was the oldest diocese in Persia. It was said to have been founded by the apostle Mari in the first century, several decades before the establishment of a diocese in the Persian capital Seleucia-Ctesiphon.^[6] Although a first-century foundation date is highly unlikely, the diocese of Kashkar was certainly one of the oldest dioceses of the Church of the East. The antiquity of the diocese and its claim to an apostolic foundation were recognised at the synod of Isaac in 410, when it was ranked second after the patriarchal diocese of Seleucia-Ctesiphon and its bishop was appointed guardian of the patriarchal throne (natar kursya).^[7]

The earliest-known bishop of Kashkar was ʿAbdishoʿ, who was one of several Persian bishops who opposed the claim to precedence put forward by the bishop Papa of Seleucia-Ctesiphon in 315.^[8] The last-known bishop of Kashkar was Sabrishoʿ, who was transferred from the diocese of Qaimar to Kashkar by the patriarch Eliya III (1176–90).^[9] By 1222 the guardianship of the vacant patriarchal throne, for centuries a privilege of the bishops of Kashkar, was in the hands of the metropolitans of Beth Huzaye.^[10]

The East Syrian diocese of Hirta (al-Hira, الحيرة) is first attested in 410, but may have been a fourth-century foundation. Its last-known bishop, Yohannan Bar Nazuk, became patriarch in 1012.

Baghdad, the capital of the ʿAbbasid caliphate, was the seat of the East Syrian patriarchs between the eighth and thirteenth centuries, and is frequently mentioned in the various literary sources in connection with the ceremonies attending their elections, consecrations, and burials. These sources mention several East Syrian monasteries and churches in or near Baghdad used as residences by the East Syrian patriarchs at different periods, and the relevant references have been conveniently collected by the French scholar J. M. Fiey, who also precisely localised most of the sites concerned. The patriarchal residences included the monastery of Klilishoʿ, also called 'the patriarchal monastery' (Dair al-Jathaliq), residence and burial place of the patriarch Timothy I (780–823) and several of his ninth-century successors; the monastery of Mar Pethion, residence of the patriarch Sabrishoʿ II (831–5); the church of Asbagh in the al-Shammasiya quarter, residence and burial place of the patriarch Yohannan II Bar Narsaï (884–91); the nearby 'Greek Palace' (Darta d'Romaye, Dar al-Rum), residence and burial place of sixteen of the seventeen patriarchs from Yohannan III (893–9) to Eliya II (1111–32); the monastery of ʿAbdon to the north of Baghdad, burial place of the patriarch Abraham III (906–37); the church of Mar Sabrishoʿ in the Suq al-Thalatha quarter, burial place of the patriarchs Bar Sawma (1134–6), Ishoʿyahb V (1149–75) and Eliya III (1176–90); the church of Mart Maryam of Karkh, residence and burial place of the patriarchs Yahballaha II (1190–1222), Sabrishoʿ IV (1222–4) and Sabrishoʿ V (1226–56); and the palace of Duwaidar ʿAla al-Din, burial place of the patriarchs Makkikha II (1257–65) and Denha I (1265–81).^[75]

Makkikha II was the last East Syrian patriarch to reside permanently in Baghdad. Baghdad's Christian population was spared by the Mongols when the city was captured and sacked in 1259, but the Mongol defeat at ʿAin Jalut in 1261 was followed by a Moslem reaction against the Christians of the caliphate. There were violent Moslem demonstrations in 1268 and 1269 in Baghdad, which forced the patriarch Denha I, consecrated in Baghdad in 1265, to withdraw first to Erbil and finally to Eshnuq. He died quite by chance in Baghdad in 1281, during his first visit to the city for sixteen years, and was probably the last East Syrian patriarch to be buried there. His successor Yahballaha III was consecrated in Baghdad in 1281, but also avoided the city for much of his reign, preferring to reside first in Eshnuq and finally in Maragha. However, a poem written in Karamlish in 1295 mentions that he restored the chapels and apartments in the Greek Palace, probably during the reign of the sympathetic il-khan Arghun, and built a "very beautiful gallery for counsel, recreation, and the reunions of the fathers".

The accession of the il-khan Ghazan in 1295 was followed immediately by a persecution of Christians in Baghdad and several other cities, in which a number of churches were confiscated. In Baghdad most churches were spared in return for bribes, but a new church built by Makkikha II was confiscated and turned into a mosque. The Moslems also recovered the palace of Duwaidar ʿAla al-Din, which had been taken from them and given to Makkikha II by Hulegu after the city's capture in 1259, and required the East Syrians to remove for reburial elsewhere the remains of the patriarchs Makkikha II and Denha I and other prominent clerics and monks buried there. Yahballaha III does not appear to have revisited Baghdad after these events, and after his death in 1317 was buried in Maragha.
