The historical distinctiveness of the Assyrian Church of the East resulted from the series of complex processes and events that occurred within the Church of the East during the transitional period that started in the middle of the 16th century, and lasted until the beginning of the 19th century. That turbulent period was marked by several consequent splits and mergers, resulting in the creation of separate branches and rival patriarchal lines. During the entire period, one of the main questions of dispute was the union with the

After some deliberation, the Pope decided to appoint Yohannan Sulaqa as "Patriarch of Babylon" and named the breakaway Church as 'The Church of Assyria and Mosul" in April 1553. Upon consecration, Yohannan Sulaqa took the name ''Shimun'' and by the end of the year he returned to his homeland. He started to organize the pro-Catholic party by appointing several metropolitans and bishops.


The senior Eliya line of Alqosh

Union with Rome was actively opposed by Patriarch Shemon VII Ishoyahb, who continued to reside in the Rabban Hormizd Monastery near the ancient Assyrian town of
Alqosh Alqosh (, , , alternatively spelled Alkosh, Alqoš, or Alqush) is a town in the Nineveh Plains of northern Iraq, a sub-district of the Tel Kaif District situated 45 km north of the city of Mosul. The inhabitants of Alqosh are Assyrian peopl ...
. He was succeeded by his nephew Eliya (1558–1591), who was designated as Eliya "VII" in older historiography, but renumbered as Eliya "VI" in recent scholarly works. The same renumbering was applied to his successors, who all took the same name thus creating the ''Eliya line''. During his patriarchal rule, the ''Eliya line'' preserved its traditional christology and full ecclesiastical independence. His successor was Patriarch Eliya VII (VIII) (1591–1617), who negotiated on several occasions with the Catholic Church, in 1605 and 1610, and again in 1615–1616, but without any conclusion. Further negotiations were abandoned by the next Patriarch Eliya VIII (IX) (1617–1660). David Wilmshurst noted that his successor, Patriarch Eliya IX (X) (1660–1700) also was a "vigorous defender of the traditional faith". The Eliya line of traditionalist Patriarchs continued throughout the entire 18th century, residing in the ancient Monastery of Rabban Hormizd, which was eventually attacked and looted by muslim Turks in 1743, at the beginning of the
Ottoman–Persian War (1743–1746) The Ottoman–Persian War of 1743–1746 or Ottoman–Iranian War of 1743–1746 was fought between the Ottoman Empire and Afsharid Iran. Background Persia attempted to ratify the Treaty of Constantinople (1736), Treaty of Constantinople, by ...

Christian communities and monasteries and taking their land, often with Ottoman support. Patriarchs Eliya X (XI) (1700–1722) and Eliya XI (XII) (1722–1778) tried to improve the increasingly worsening position of their Christian flock by staying loyal to Ottoman authorities, but the local administration was frequently unable to provide effective protection. The Eliya line of traditionalist Patriarchs ended in 1804 with the death of Eliya XII (XIII) (1778–1804).


The junior Shimun line of Qochanis

During the second half of the 16th century, traditionalist patriarchs of the Eliya line were faced with the continuous presence of the pro-Catholic movement, led by successors of Shimun VIII Yohannan Sulaqa. After his death in 1555, the newly established line of patriarchs who were united with the Catholic Church was continued by Abdisho IV Maron (1555–1570), who remained in

in 1562. Soon after his death, connections with Rome were weakened for the first time during the tenure of Patriarch Yahballaha IV who did not seek confirmation from the Pope. That interlude was ended by his successor Shimun IX Dinkha (1580–1600) who restored full communion with the Catholic Church, and was officially confirmed by the Pope in 1584. After his death, the patriarchal office was made hereditary, and Patriarchs of this line continued to use the name ''Shimun'', thus creating the Shimun line. Hereditary succession was not acceptable to Rome, and during the tenure of the next Patriarch Shimun X Eliyah (1600–1638) ties with the Catholic Church were loosened again. In 1616, Shimun X signed a traditional profession of faith that was not accepted by the Pope, leaving the Patriarch without Rome's confirmation. His successor Shimun XI Eshuyow (1638–1656) restored communion with the Catholic Church as late as 1653, eventually receiving confirmation from the Pope. By that time, the movement towards full commitment to the traditional faith was constantly growing stronger within the Shimun line. When the next Patriarch Shimun XII Yoalaha decided to send his profession of faith to the Pope, he was deposed by his bishops because of his pro-Catholic attitude. The Pope tried to intervene on his behalf, but without success. Final resolution of conflicts within the Shimun line occurred under the next Patriarch Shimun XIII Dinkha (1662–1700), who definitively broke communion with the Catholic Church. In 1670, he gave a traditionalist reply to an approach that was made from the Pope, and by 1672 all connections with the Catholic Church were terminated. At the same time, Patriarch Shimun XIII moved his seat from Amid to Qochanis. After the final return to the traditional faith, Patriarchs of the Shimun line decided to keep their independence and after that time there were two independent lines of traditional patriarchs: the senior Eliya line in Alqosh and the junior Shimun line in Qochanis. Such division was additionally caused by the complex structure of local Assyrian communities, traditionally organized as tribal confederations with each

Consolidation of remaining branches

In 1780, at the beginning of the patriarchal tenure of Eliya XII (XIII) (1778–1804), a group seceded from the Eliya line in Alqosh and elected
Yohannan Hormizd Yohannan VIII Hormizd (often referred to by European missionaries as ''John Hormez'' or ''Hanna Hormizd'') (1760–1838) was the last hereditary patriarch of the Eliya line of the Church of the East and the first patriarch of a united Chaldea ...

, in 1783. Only after the death in 1827 of the last representative of the Josephite line, Joseph V Augustine Hindi, was Yohannan recognized as the Chaldean Catholic Patriarch by the Pope, in 1830. By this official appointment, the final merger of various factions committed to the union with the Catholic Church was achieved, thus forming the modern Chaldean Catholic Church. At the same time, the long coexistence and rivalry between two traditionalist patriarchal branches — the senior Eliya line of Alqosh and the junior Shimun line of Qochanis — ended in 1804 when the last primate of the Eliya line, Patriarch Eliya XII (XIII) died and was buried in the ancient Rabban Hormizd Monastery. His branch decided not to elect a new patriarch, thus enabling the remaining patriarch Shimun XVI Yohannan (1780–1820) of the Shimun line to become the sole primate of both Assyrian traditionalist branches. Consolidated after 1804, the reunited traditionalist Church led by patriarchs of the Shimun line became widely known as the "Assyrian Church of the East". Still based in Qodchanis, Assyrian Patriarch Shimun XVI Yohannan was not able to secure control over the traditional seat of the former Eliya line in the ancient Rabban Hormizd Monastery; and around 1808 that venerated monastic institution passed to the Chaldean Catholics. The next Assyrian Patriarch Shimun XVII Abraham (1820–1861) also governed his church from Qodshanis. During years marked by political turbulence, he tried to maintain good relations with the local Ottoman authorities. In 1843, he was faced with renewed hostilities from Kurdish warlords, who attacked and looted many Christian villages, killing 10,000 Christian men and taking away women and children as captives. The patriarch himself was forced to take temporary refuge in

By the end of the 19th century, the Assyrian Church of the East consolidated itself as the sole representative of all traditionalist Assyrians. It also managed to secure a certain level of autonomy within the highly complex system of Ottoman local governance in the bordering regions. On several occasions, Assyrian patriarchs refused to enter communion with the Catholic Church or merge with the Chaldean Catholic Church. On the other hand, by the end of the 19th century some of its communities were converted to

Later, in 1918, after the murder of their ''de facto'' leader and Patriarch Shimun XIX Benyamin and 150 of his followers during a negotiation, fearing further massacres at the hands of the Turks and Kurds, most of the survivors fled by train from Iran into what was to become Iraq.

. In 1972, Shimun decided to step down as patriarch, and the following year he got married, in contravention to longstanding church custom. This led to a synod in 1973 in which further reforms were introduced, the most significant of which included the permanent abolition of hereditary succession — a practice introduced in the middle of the fifteenth century by Patriarch Shemon IV Basidi (who had died in 1497) — and it was also decided that Shimun should be reinstated. The second matter was supposed to be settled at another synod in 1975; however, Shimun was assassinated in November 1975 by an estranged relative before this could take place.

. The use and exact meaning of that term has been the subject of many debates, not only throughout history but also in modern times, since the Assyrian Church of the East has distinctive views on several Christological questions and claims that its theological doctrines and traditions are essentially Orthodox, while admitting the need for further inter-Christian dialogue that would resolve various questions in the field of comparative Christological terminology. The Nestorian nature of Assyrian Christianity remains a matter of contention. Elements of Nestorian doctrine were explicitly repudiated by Patriarch Dinkha IV on the occasion of his accession in 1976. The Christology of the Church of the East has its roots in the Antiochene theological tradition of the early church. The founders of Assyrian theology are Diodorus of Tarsus and

In the controversy that followed the Council of Ephesus, the term "Nestorian" was applied to all doctrine upholding a strictly Antiochene Christology. In consequence, the Church of the East was labelled Nestorian, though its official Christology was in fact defined by Babai the Great, at the council that was held in 612.
