The Church of the East (Syriac: ܥܕܬܐ ܕܡܕܢܚܐ Ēdtāʾ d-Maḏenḥā), also known as the Nestorian Church,[note 1] is a Christian church within the Syriac tradition of Eastern Christianity. It was the Christian church of the Sassanian Empire, and quickly spread widely through Asia. Between the 9th and 14th centuries, the Church of the East represented the world's largest Christian church in terms of geographical extent, with dioceses stretching from the Mediterranean Sea to China and India. Several modern churches claim continuity with the historical Church of the East.
The background of the establishment of the Church of the East is considered to be the first and third centuries among the early Assyrian Christian communities in the Parthian Empire's province of Mesopotamia, the Sasanian province of Asōristān (Assyria), and the small independent Neo-Assyrian kingdoms of Osroene, Adiabene, Beth Garmai, Beth Nuhadra and Assur.
The Church of the East was headed by the Patriarch of the East, continuing a line that, according to tradition, stretched back to the Apostolic Age. Liturgically, the church adhered to the East Syrian Rite, and theologically, it adopted the doctrine of Nestorianism, which emphasises the separateness of the divine and human natures of Jesus. This doctrine and its namesake, Nestorius (386–451), were condemned by the Council of Ephesus in 431, leading to the Nestorian Schism and a subsequent exodus of Nestorius' supporters to Sasanian Persia. The existing Christians in Persia welcomed these refugees and gradually adopted Nestorian doctrine by the 5th century, leading the Church of Persia to be known alternately as the Nestorian Church.
The church grew rapidly under the Sassanians, and following the Muslim conquest of Persia (633–654) it was designated as a protected dhimmi community under Muslim rule. From the 6th century it expanded greatly, establishing communities in India (the Saint Thomas Christians), among the Mongols in Central Asia, and in China, which became home to a thriving community under the Tang dynasty from the 7th to the 9th century. In the 13th and 14th centuries the church experienced a final period of expansion under the Mongol Empire, where influential Nestorian Christians sat in the Mongol court. At its height, the Church had spread from its heartland in Upper Mesopotamia to as far afield as China, Mongolia, Central Asia, Asia Minor, the Arabian peninsula and India.
From its peak of geographical extent, the church experienced a rapid period of decline starting in the 14th century, due in large part to outside influences. The Mongol Empire dissolved into civil war, the Chinese Ming dynasty overthrew the Mongols (1368) and ejected Christians and other foreign influences from China, and many Mongols in Central Asia converted to Islam. The Muslim Mongol leader Timur (1336–1405) nearly eradicated the remaining Christians in Persia; thereafter, Nestorian Christianity remained largely confined to Upper Mesopotamia and to the Malabar Coast of India.
During the Schism of 1552, Patriarch Shimun VIII Yohannan Sulaqarival entered into full communion with the Holy See and the Catholic Church, leading to the emergence of the Chaldean Catholic Church, an Eastern Catholic Church formed out of the Church of the East, today with 640,828 members. However, Patriarch Shimun VIII's successors in the 17th and 18th centuries presided over a time of turbulence, with lines of varying connections to the Papacy. In one of these patriarchal claimants, hereditary status of the office was reintroduced and relations with Rome formally broken, with this line eventually forming the Assyrian Church of the East in 1692, today with 170,000 members, who since also claim patriarchal lineage from the Church of the East.

Organization and structure
The Church of the East was headed by the Patriarch of the East, an office that traces its origin to the Apostolic Age. The head of the church also bears the title "Catholicos". Like the churches from which it developed, the Church of the East has an ordained clergy divided into the three traditional orders of deacon, priest (or presbyter), and bishop. Also like other churches, it has an episcopal polity: organisation by dioceses, each headed by a bishop and made up of several individual parish communities overseen by priests. Dioceses are organised into provinces under the authority of a metropolitan bishop. The office of metropolitan bishop is an important one, and comes with additional duties and powers; canonically, only metropolitans can consecrate a patriarch. The Patriarch also has the charge of the Province of the Patriarch.
For most of its history the church had six or so Interior Provinces in its heartland in northern Mesopotamia, southeastern Anatolia, and northwestern Iran and an increasing number of Exterior Provinces elsewhere. Most of these latter were located farther afield within the territory of the Sasanian Empire (and later the Caliphate), but very early on, provinces formed beyond the empire's borders as well. By the 10th century, the church had between 20 and 30 metropolitan provinces including in China and India. The Chinese provinces were lost in the 11th century, and in the subsequent centuries, other exterior provinces went into decline as well. However, in the 13th century, during the Mongol Empire, the church added two new metropolitan provinces in North China, Tangut and Katai and Ong.
Nestorianism and naming conventions
The Church of the East became associated with Nestorianism, a Christological doctrine attributed to Nestorius, Patriarch of Constantinople from 428 – 431 AD, which emphasises the disunion between the human and divine natures of Jesus. Although the "Nestorian" label was initially a theological one, applied to followers of the Nestorian doctrine, it was soon applied to all associated East Syrian Rite churches with little regard for theological consideration. While often used disparagingly in the West to emphasise the Church of the East's connections to a heretical doctrine, many writers of the Middle Ages and since have simply used the label descriptively, as a neutral and conventional term for the church. Other names for the church include "Persian Church", "Syriac" or "Syrian" (often distinguished as East Syriac/Syrian), and "Assyrian".
Nestorius's doctrine represented the culmination of a philosophical current developed by scholars at the School of Antioch, most notably Nestorius's mentor Theodore of Mopsuestia. This became a source of controversy when Nestorius publicly challenged usage of the title Theotokos (literally, "Bearer of God") for the Virgin Mary. He suggested that the title denied Christ's full humanity, arguing instead that Jesus had two loosely joined natures, the divine Logos and the human Jesus, and proposed Christotokos (literally, "Bearer of the Christ") as a more suitable alternative title. These statements drew criticism from other prominent churchmen, particularly from Cyril, Patriarch of Alexandria, leading to the First Council of Ephesus in 431, which condemned Nestorius for heresy and deposed him as patriarch. Nestorianism was officially anathematised, a ruling reiterated at the Council of Chalcedon in 451. However, a number of churches, particularly those associated with the School of Edessa in Assyria and northern Mesopotamia, supported Nestorius—though not necessarily the doctrine ascribed to him—and broke with the churches of the Roman and Byzantine Empires. Many of Nestorius' supporters relocated to Sasanian Persia. These events are known as the Nestorian Schism.
In modern times some scholars have sought to avoid the Nestorian label, preferring "Church of the East" or one of the other alternatives. This is due both to the term's derogatory connotations, and because it implies a stronger connection to Nestorian doctrine than may have historically existed. As Wilhelm Baum and Dietmar W. Winkler said, "Nestorius himself was no Nestorian" in terms of doctrine. Even from the beginning, not all churches called "Nestorian" adhered to the Nestorian doctrine; in China, it has been noted that none of the various sources for the local Nestorian church refer to Christ as having two natures. As such, in 2006 an academic conference changed its name from "Research on Nestorianism in China", explaining in the Preface, "...it was decided not to keep the term "Nestorianism" in the title of the future conferences and the present book, but to use the term Church of the East, which is correct and wide enough to cover the whole field of the research."
The 2000 work, The Ecclesiastical Organisation of the Church of the East, 1318–1913, offers an explanation in the first chapter:
The terminology used in this study deserves a word of explanation. Until recently the Church of the East was usually called the 'Nestorian' church, and East Syrian Christians were either 'Nestorians' or (after the schism of 1552) by the ethnic and geographic misnomer 'Chaldeans'. During the period covered in this study, the word 'Nestorian' was used both as a term of abuse by those who disapproved of the traditional East Syrian theology, as a term of pride by many of its defenders (including Abdisho of Nisibis in 1318, the Mosul patriarch Eliya X Yohannan Marogin in 1672, and the Qudshanis patriarch Shem'on XVII Abraham in 1842), and as a neutral and convenient descriptive term by others. Nowadays it is generally felt that the term carries a stigma, and students of the Church of the East are advised to avoid its use. In this thesis the theologically neutral adjective 'East Syrian' has been used wherever possible, and the term 'traditionalist' to distinguish the non-Catholic branch of the Church of the East after the schism of 1552. The modern term 'Assyrian', often used in the same sense, was unknown for most of the period covered in this study, and has been avoided.
The Assyrian Church of the East has shunned the "Nestorian" label in recent times. The church's former head, Catholicos-Patriarch Mar Dinkha IV, explicitly rejected the term on the occasion of his consecration in 1976.
The Peshitta, in some cases lightly revised and with missing books added, is the standard Syriac Bible for churches in the Syriac tradition: the Syriac Orthodox Church, the Syrian Catholic Church, the Assyrian Church of the East, the Ancient Church of the East, the Chaldean Catholic Church, the Maronites, the Malankara Orthodox Syrian Church, the Syro-Malabar Catholic Church and the Syro-Malankara Catholic Church.
The Old Testament of the Peshitta was translated from Hebrew, although the date and circumstances of this are not entirely clear. The translators may have been Syriac-speaking Jews or early Jewish converts to Christianity. The translation could have been done separately for different texts, and the whole work was probably done by the second century.
The New Testament of the Peshitta, which originally excluded certain disputed books (Second Epistle of Peter, Second Epistle of John, Third Epistle of John, Epistle of Jude, Book of Revelation), had become the standard by the early 5th century.
Although the Nestorian community traced their history to the 1st century, the Church of the East first achieved official state recognition from the Sassanid Empire in the 4th century with the accession of Yazdegerd I (reigned 399–420) to the throne of the Sasanian Empire. In 410 the Synod of Seleucia-Ctesiphon, held at the Sasanian capital, allowed the Church's leading bishops to elect a formal Catholicos (leader). Catholicos Isaac was required both to lead the Assyrian Christian community, and to answer on its behalf to the Sasanian emperor.[need quotation to verify]
Under pressure from the Sasanian Emperor, the Church of the East sought to increasingly distance itself from the Greek Orthodox Church (at the time being known as the church of the Eastern Roman Empire). Therefore, In 424, the bishops of the Sasanian Empire met in council under the leadership of Catholicos Dadishoʿ (421–456) and determined that they would not, henceforth, refer disciplinary or theological problems to any external power, and especially not to any bishop or Church Council in the Roman Empire.[need quotation to verify]
Thus, the Mesopotamian churches did not send representatives to the various Church Councils attended by representatives of the "Western Church". Accordingly, the leaders of the Church of the East did not feel bound by any decisions of what came to be regarded as Roman Imperial Councils. Despite this, the Creed and Canons of the First Council of Nicaea of 325, affirming the full divinity of Christ, were formally accepted at the Synod of Seleucia-Ctesiphon. The Church's understanding of the term hypostasis differs from the definition of the term offered at the Council of Chalcedon of 451. For this reason, the Assyrian Church has never approved the Chalcedonian definition.
The theological controversy that followed the Council of Ephesus in 431 proved a turning point in the Church's history. The Council condemned as heretical the Christology of Nestorius, whose reluctance to accord the Virgin Mary the title Theotokos "God-bearer, Mother of God" was taken as evidence that he believed two separate persons (as opposed to two united natures) to be present within Christ. (For the theological issues at stake, see Assyrian Church of the East and Nestorianism.)
The Sasanian Emperor, hostile to the Byzantines, saw the opportunity to ensure the loyalty of his Christian subjects and lent support to the Nestorian Schism. The Emperor took steps to cement the primacy of the Nestorian party within the Assyrian Church of the East, granting its members his protection, and executing the pro-Roman Catholicos Babowai in 484, replacing him with the Nestorian Bishop of Nisibis, Barsauma. The Catholicos-Patriarch Babai (497–503) confirmed the association of the Assyrian Church with Nestorianism.
Parthian and Sassanian periods
Christians were already forming communities in Mesopotamia as early as the 1st century under the Parthian Empire. In 266, the area was annexed by the Persian Sassanian Empire (becoming the province of Asōristān), and there were significant Christian communities in Upper Mesopotamia, Elam, and Fars. The Church of the East traced its origins ultimately to the evangelical activity of Thaddeus of Edessa, Mari and Thomas the Apostle. While under the jurisdiction of the patriarchate of Antioch, leadership and structure remained disorganised until 315 when Papa bar Aggai (310–329), bishop of Seleucia-Ctesiphon, imposed the primacy of his see over the other Mesopotamian and Persian bishoprics which were grouped together into the Catholicate of Seleucia-Ctesiphon; Papa took the title of Catholicos of the East, or universal leader. This position received an additional title in 410, becoming Catholicos and Patriarch of the East.
These early Christian communities in Mesopotamia, Elam, and Fars were reinforced in the 4th and 5th centuries by large-scale deportations of Christians from the eastern Roman Empire. However, the Persian Church faced several severe persecutions, notably during the reign of Shapur II (339–79), from the Zoroastrian majority who accused it of Roman leanings. Shapur II attempted to dismantle the Catholicate's structure and put to death some of the clergy including the catholicoi Simeon bar Sabba'e (341), Shahdost (342), and Barba'shmin (346). Afterward, the office of Catholicos lay vacant nearly 20 years (346–363). In 363, under the terms of a peace treaty, Nisibis was ceded to the Persians, causing Ephrem the Syrian, accompanied by a number of teachers, to leave the School of Nisibis for Edessa still in Roman territory. The church grew considerably during the Sasanian period, but the pressure of persecution led the Catholicos Dadisho I in 424 to convene the Synod of Markabta at Seleucia and declare the Catholicate independent from the Patriarch of Antioch.
Meanwhile, in the Roman Empire, the Nestorian Schism had led many of Nestorius' supporters to relocate to the Persian Empire, mainly around the theological School of Nisibis. The Persian Church increasingly aligned itself with the Nestorian schismatics, a measure encouraged by the Zoroastrian ruling class. The church became increasingly Nestorian in doctrine over the next decades, furthering the divide between Roman and Nestorian Christianity. In 486 the Metropolitan of Nisibis, Barsauma, convened the Synod of Beth Lapat where he publicly accepted Nestorius' mentor, Theodore of Mopsuestia, as a spiritual authority. In 489, when the School of Edessa in Mesopotamia was closed by Byzantine Emperor Zeno for its Nestorian teachings, the school relocated to its original home of Nisibis, becoming again the School of Nisibis, leading to a wave of Nestorian immigration into the Persian Empire. The Patriarch of the East Mar Babai I (497–502) reiterated and expanded upon his predecessors' esteem for Theodore, solidifying the church's adoption of Nestorianism.
Now firmly established in the Persian Empire, with centres in Nisibis, Ctesiphon, and Gundeshapur, and several metropolitan sees, the Church of the East began to branch out beyond the Persian Sasanian Empire. However, through the 6th century the church was frequently beset with internal strife and persecution from the Zoroastrians. The infighting led to a schism, which lasted from 521 until around 539, when the issues were resolved. However, immediately afterward Byzantine-Persian conflict led to a renewed persecution of the church by the Sasanid King Khosrau I; this ended in 545. The church survived these trials under the guidance of Patriarch Mar Abba I, who had converted to Christianity from Zoroastrianism.
By the end of the 5th century and the middle of the 6th, the area occupied by the Church of the East included "all the countries to the east and those immediately to the west of the Euphrates", including Sasanian Persia, Arabia, Socotra, Mesopotamia, Media, Bactria, Hyrcania, and India; and possibly also to places called Calliana, Male, and Sielediva (Ceylon). Beneath the Patriarch in the hierarchy were nine metropolitans, and clergy were recorded among the Huns, in Persarmenia, Media, and the island of Dioscoris in the Indian Ocean.
After the Sassanian Empire was conquered by Muslim Arabs in 644, the newly established Rashidun Caliphate designated the Church of the East as an official dhimmi minority group headed by the Patriarch of the East. As with all other Christian and Jewish groups given the same status, the Church was restricted within the Caliphate, but also given a degree of protection. Nestorians were not permitted to proselytise or attempt to convert Muslims, but their missionaries were otherwise given a free hand, and they increased missionary efforts farther afield. Missionaries established dioceses in India (the Saint Thomas Christians). They made some advances in Egypt, despite the strong Monophysite presence there, and they entered Central Asia, where they had significant success converting local Tartar tribes. Nestorian missionaries were firmly established in China during the early part of the Tang Dynasty (618–907); the Chinese source known as the Nestorian Stele describes a mission under a proselyte named Alopen as introducing Nestorian Christianity to China in 635. In the 7th century, the Church had grown to have two Nestorian archbishops, and over 20 bishops east of the Iranian border of the Oxus River.
The patriarch Timothy I (780–823), a contemporary of the caliph Harun al-Rashid, took a particularly keen interest in the missionary expansion of the Church of the East. He is known to have consecrated metropolitans for Damascus, for Armenia, for Dailam and Gilan in Azerbaijan, for Rai in Tabaristan, for Sarbaz in Segestan, for the Turks of Central Asia, for China, and possibly also for Tibet. He also detached India from the metropolitan province of Fars and made it a separate metropolitan province, known as India. By the 10th century the Church of the East had a number of dioceses stretching from across the Caliphate's territories to India and China.
Nestorian Christians made substantial contributions to the Islamic Umayyad and Abbasid Caliphates, particularly in translating the works of the ancient Greek philosophers to Syriac and Arabic. Nestorians made their own contributions to philosophy, science (such as Hunayn ibn Ishaq, Qusta ibn Luqa, Masawaiyh, Patriarch Eutychius, Jabril ibn Bukhtishu) and theology (such as Tatian, Bar Daisan, Babai the Great, Nestorius, Toma bar Yacoub). The personal physicians of the Abbasid Caliphs were often Assyrian Christians such as the long serving Bukhtishu dynasty.
After the split with the Western World and synthesis with Nestorianism, the Church of the East expanded rapidly due to missionary works during the Medieval period. During the period between 500–1400 the geographical horizons of the Church of the East extended well beyond its heartland in present-day northern Iraq, north eastern Syria and south eastern Turkey. Communities sprang up throughout Central Asia, and missionaries from Assyria and Mesopotamia took the Christian faith as far as China, with a primary indicator of their missionary work being the Nestorian Stele, a Christian tablet written in Chinese script found in China dating to 781 AD. Their most important conversion, however, was of the Saint Thomas Christians of the Malabar Coast in India, as they are now the largest group of non ethnically Assyrian Christians on earth, with around 10 million followers when all denominations are added together and their own diaspora is included. The St Thomas Christians were believed by tradition to have been converted by St Thomas, and were in communion with the Church of the East until the end of the medieval period.
The Saint Thomas Christian community of Kerala, India, who as per tradition trace their origins to the evangelism of Thomas the Apostle, had a long connection with the Church of the East. The earliest known organised Christian presence in Kerala dates to the 3rd century, when Nestorian Christian settlers and missionaries from Persia settled in the region. The Saint Thomas Christians traditionally credit the mission of Thomas of Cana, a Nestorian from the Middle East, with the further expansion of their community. From at least the early 4th century, the Patriarch of the Church of the East provided the Saint Thomas Christians with clergy, holy texts, and ecclesiastical infrastructure, and around 650 Patriarch Ishoyahb III solidified the church's jurisdiction in India. In the 8th century Patriarch Timothy I organised the community as the Ecclesiastical Province of India, one of the church's Provinces of the Exterior. After this point the Province of India was headed by a metropolitan bishop, provided from Persia, who oversaw a varying number of bishops as well as a native Archdeacon, who had authority over the clergy and also wielded a great amount of secular power. The metropolitan see was probably in Cranganore, or (perhaps nominally) in Mylapore, where the shrine of Thomas was located.
In the 12th century Indian Nestorianism engaged the Western imagination in the figure of Prester John, supposedly a Nestorian ruler of India who held the offices of both king and priest. The geographically remote Malabar church survived the decay of the Nestorian hierarchy elsewhere, enduring until the 16th century when the Portuguese arrived in India. The Portuguese at first accepted the Nestorian sect, but by the end of the century they had determined to actively bring the Saint Thomas Christians into full communion with Rome under the Latin Rite. They installed Portuguese bishops over the local sees and made liturgical changes to accord with the Latin practice. In 1599 the Synod of Diamper, overseen by Aleixo de Menezes, Archbishop of Goa, led to a revolt among the Saint Thomas Christians; the majority of them broke with the Catholic Church and vowed never to submit to the Portuguese in the Coonan Cross Oath of 1653. In 1661 Pope Alexander VII responded by sending a delegation of Carmelites headed by Chaldean Catholics to re-establish the East Syrian rites under an Eastern Catholic hierarchy; by the next year, 84 of the 116 communities returned, forming the Syro-Malabar Catholic Church. The rest, which became known as the Malankara Church, soon entered into communion with the Syriac Orthodox Church; from the Malankara Church has also come the Syro-Malankara Catholic Church.
Christianity reached China by 635, and its relics can still be seen in Chinese cities such as Xi'an. The Nestorian Stele, set up on 7 January 781 at the then-capital of Chang'an, attributes the introduction of Christianity to a mission under a Persian cleric named Alopen in 635, in the reign of Emperor Taizong of Tang during the Tang dynasty. The inscription on the Nestorian Stele, whose dating formula mentions the patriarch Hnanishoʿ II (773–80), gives the names of several prominent Christians in China, including the metropolitan Adam, the bishop Yohannan, the 'country-bishops' Yazdbuzid and Sargis and the archdeacons Gigoi of Khumdan (Chang'an) and Gabriel of Sarag (Loyang). The names of around seventy monks are also listed.
Nestorian Christianity thrived in China for approximately 200 years, but then faced persecution from Emperor Wuzong of Tang (reigned 840–846). He suppressed all foreign religions, including Buddhism and Christianity, causing it to decline sharply in China. A Syrian monk visiting China a few decades later described many churches in ruin. The Church disappeared from China in the early 10th century, coinciding with the collapse of the Tang dynasty and the tumult of the next years (the Five Dynasties and Ten Kingdoms period).
Christianity in China experienced a significant revival during the Mongol-created Yuan dynasty, established after the Mongols had conquered China in the 13th century. Marco Polo in the 13th century and other medieval Western writers described many Nestorian communities remaining in China and Mongolia; however, they clearly were not as vibrant as they had been during Tang times.
Mongolia and Central Asia
The Church of the East enjoyed a final period of expansion under the Mongols. Several Mongol tribes had already been converted by Nestorian missionaries in the 7th century, and Christianity was therefore a major influence in the Mongol Empire. Genghis Khan was a shamanist, but his sons took Christian wives from the powerful Kerait clan, as did their sons in turn. During the rule of Genghis's grandson, the Great Khan Mongke, Nestorian Christianity was the primary religious influence in the Empire, and this also carried over to Mongol-conquered China, during the Yuan Dynasty. It was at this point, in the late 13th century, that the Church of the East reached its greatest geographical extent. But Mongol power was already waning, as the Empire dissolved into civil war, and it reached a turning point in 1295, when Ghazan, the Mongol ruler of the Ilkhanate, made a formal conversion to Islam when he took the throne.
Jerusalem and Cyprus
Rabban Bar Sauma had initially conceived of his journey to the West as a pilgrimage to Jerusalem, so it is possible that there was a Nestorian presence in the city ca.1300. There was certainly a recognisable Nestorian presence at the Holy Sepulchre from the 1348 through 1575, as contemporary Franciscan accounts indicate. At Famagusta, Cyprus, a Nestorian community was established just before 1300, and a church was built for them ca.1339.
The end to the Churches expansion came in 1400, when the massacres of Christians by Timur (1336–1405) destroyed many bishoprics, including the ancient Assyrian city and cultural capital of Ashur and from Tkrit, and the complete the eradication of Christians from much of central and southern Mesopotamia/Iraq.
Due to this disaster, the Church of the East, which had previously extended as far as China, was largely reduced to an Assyrian Neo-Aramaic-speaking remnant living in its original heartland in Upper Mesopotamia.(With the exception of the St Thomas Christians in India) The Assyrian churches area of influence was from this point up until the Assyrian genocide a triangular area between Amid (modern Diyarbakır), Mêrdîn (modern Mardin), and Edessa to the west; Salmas to the east; Hakkari and Harran to the north; and Mosul, Kirkuk, and Arbela (modern Erbil) to the south; essentially a region comprising, in modern terms, northern Iraq, south east Turkey, north east Syria and the north western fringe of Iran.
Due to the destruction of Assur, The See was moved to the Assyrian town of Alqosh (Kara Akosh) during the 1400s, and Shimun IV Basidi (1437–1493) was appointed Patriarch, establishing a new, hereditary line of succession.
Collapse of the exterior provinces
The "exterior provinces" of the Church of the East, with the important exception of India, collapsed during the second half of the fourteenth century. Although little is known of the circumstances of the demise of the Nestorian dioceses in Central Asia (which may never have fully recovered from the destruction caused by the Mongols a century earlier), it probably stemmed from a combination of persecution, disease, and isolation.
The blame for the destruction of the Nestorian communities east of northern Iraq has often been thrown upon the Turco-Mongol leader of the Timurid Empire, Tamerlane, whose campaigns during the 1390s spread havoc throughout Persia and Central Asia. However, in many parts of Central Asia, Christianity had died out decades before Tamerlane's campaigns. The surviving evidence from Central Asia, including a large number of dated graves, indicates that the crisis for the Church of the East occurred in the 1340s rather than the 1390s. Several contemporary observers, including the papal envoy Giovanni de' Marignolli, mention the murder of a Latin bishop in 1339 or 1340 by a Muslim mob in Almaliq, the chief city of Tangut, and the forcible conversion of the city's Christians to Islam.
At the end of the 19th century, tombstones in two East Syrian cemeteries were discovered[by whom?] and dated in Mongolia. They dated from 1342, and several commemorated deaths during a Black Death outbreak in 1338. In China the last references to Nestorian and Latin Christians date from the 1350s. It is likely[original research?] that all foreign Christians were expelled from China soon after the revolution of 1368, which replaced Mongol Yuan dynasty rule in China with the xenophobic Ming dynasty.
By the 15th century, Nestorian Christianity was largely confined to the Eastern Aramaic-speaking Assyrian communities of northern Mesopotamia, in and around the rough triangle formed by Mosul and Lakes Van and Urmia - the same general region where the Church of the East had first emerged between the 1st and 3rd centuries AD. Small Nestorian communities were located further west, notably in Jerusalem and Cyprus, but the Malabar Christians of India represented the only significant survival of the once-thriving exterior provinces of the Church of the East.
Schism of 1552
Around the middle of the fifteenth century the patriarch Shemʿon IV Basidi made the patriarchal succession hereditary, normally from uncle to nephew. This practice, which resulted in a shortage of eligible heirs, eventually led to a schism in the Church of the East. The patriarch Shemʿon VII Ishoʿyahb (1539–58) caused great offence at the beginning of his reign by designating his twelve-year-old nephew Khnanishoʿ as his successor, presumably because no older relatives were available. Several years later, probably because Khnanishoʿ had died in the interim, he designated as successor his fifteen-year-old brother Eliya, the future patriarch Eliya VII (1558–91). These appointments, combined with other accusations of impropriety, caused discontent throughout the church, and by 1552 Shemʿon VII Ishoʿyahb had become so unpopular that a group of bishops, principally from the Amid, Sirt and Salmas districts in northern Mesopotamia, chose a new patriarch, electing a monk named Yohannan Sulaqa, the superior of Rabban Hormizd Monastery near the Assyrian town of Alqosh. However, no bishop of metropolitan rank was available to consecrate him, as canonically required. Franciscan missionaries were already at work among the Nestorians, and they persuaded Sulaqa's supporters to legitimise their position by seeking their candidate's consecration by Pope Julius III (1550–5).
Sulaqa went to Rome to put his case in person. At Rome he made a satisfactory Catholic profession of faith and presented a letter, drafted by his supporters in Mosul, which set out his claims to be recognised as patriarch. On April 9, having satisfied the Vatican that he was a good Catholic, Sulaqa was consecrated bishop and archbishop in the basilica of Saint Peter. On April 28 he was recognised as "patriarch of Athura and Mosul" by pope Julius III in the bull Divina disponente clementia and received the pallium from the pope's hands at a secret consistory in the Vatican. These events, which marked the birth of the Chaldean Catholic Church, created a permanent schism in the Church of the East.
Sulaqa was consecrated "patriarch of Athura and Mosul" in Rome in April 1553 and returned to northern Mesopotamia towards the end of the same year. In December 1553 he obtained documents from the Ottoman authorities recognising him as an independent "Chaldean" patriarch, and in 1554, during a stay of five months in Amid, consecrated five metropolitan bishops (for the dioceses of Gazarta, Hesna d'Kifa, Amid, Mardin and Seert). Shemʿon VII Ishoʿyahb responded by consecrating two more underage members of the patriarchal family as metropolitans for Nisibis and Gazarta. He also won over the governor of ʿAmadiya, who invited Sulaqa to ʿAmadiya, imprisoned him for four months, and put him to death in January 1555.
Sees in Qochanis, Amid, and Alqosh
The connections with Rome loosened up under Shimun VIII Sulaqa's successors, who all used the patriarchal name Shimun. The last patriarch to be formally recognised by the Pope died in the 1600, and the heredity of the office was reintroduced, and thus by 1660 the Church of the East had become divided into two patriarchates, the Eliya line in Alqosh (which comprised those who had not entered into Communion with Rome) and the Shimun line. In 1672 the Patriarch of the Shimun line, Mar Shimun XIII Denha, moved his seat to the Assyrian village of Qochanis in the mountains of Hakkari. In 1692 he formally broke communion with Rome and he allegedly resumed relations with the line at Alqosh.
In the Western regions, a new start for the so-called Chaldean Patriarchate began in 1672 when Mar Joseph I, then the metropolitan of Amid, entered in communion with Rome, separating from the Patriarchal see of Alqosh. In 1681 the Holy See granted him the title of "Patriarch of the Chaldeans deprived of its patriarch" as leader of the Assyrian people who stayed in communion with Rome, and thus forming the third patriarchate of the Church of the East.
Josephite line of Amid
All Joseph I's successors took the name of Joseph. The life of this patriarchate was difficult: the leadership was continually vexed by traditionalists, while the community struggled under the tax burden imposed by the Ottoman authorities. Nevertheless, its influence expanded from the original towns of Amid and Mardin toward the area of Mosul, where they relocated the see.
Yohannan Hormizd, the last in the Eliya hereditary line in Alqosh, made a Catholic profession of faith in 1780. He entered full communion with the Roman see in 1804, but he was recognised as Patriarch by the Pope only in 1830. This merged the majority of the Patriarchate of Alqosh with the Josephite line of Amid, thus forming the modern Chaldean Catholic Church.
The Shimun line of patriarchs at Qochanis, which extended mainly in the Northern mountains, remained independent of the Chaldean Church, and the patriarchate of the present-day Assyrian Church of the East, now located in Chicago, Illinois, USA, forms the continuation of this line.
