By 1660, the Church of the East had become divided into two patriarchates:
* the largest and oldest [[episcopal see|patriarchal See]] was based at the [[Rabban Hormizd Monastery]] of [[Alqosh]]. It spread from [[Aqrah]] up to [[Amid]] and [[Nusaybin|Nisibis]], covering in the South the rich plain of [[Mosul]] (it is known also as ''Eliya'' line). Since the 15th century its Patriarchs were appointed through an hereditary system.
* the second patriarchal See was located in Khosrowa, near [[Salmas]] (from 1672 in [[Qochanis]]) and extended into the North East mountains (it is also known as the ''Shimun'' line). This patriarchal line began in 1553 when Mar [[Shimun VIII Yohannan Sulaqa|Yohannan Sulaqa]] was consecrated bishop by the [[Pope]] in 1553, but soon it lost the connections with Rome. The last patriarch of this line recognized by the [[Holy See]] was Shimun IX Dinkha (died 1600) and later there were only few correspondences through missionaries. This See reintroduced in 1600 the heredity system for patriarchs' succession, a use unacceptable for Rome. This patriarchal line still survives in the denomination today known as [[Assyrian Church of the East]].
