Catholicoi and Patriarchs of Babylon for the Chaldeans
The Shimun line
In 1553 Mar Yohannan Sulaqa, willing to separate from the Church of the East's patriarchal See of Alqosh, went to Rome asking for his appointment as patriarch: he was consecrated in St. Peter's Basilica on 9 April 1553.

- 92 Mar Yahballaha V (1572-1580)
- 93 Mar Shimun IX Dinkha (1580-1600) - moved the See in Urmia
Mar Shimun IX Dinkha was the last patriarch of the Shimun line to be formally recognized by Rome. He reintroduced the hereditary succession.

In 1692 Mar Shimun XIII Dinkha broke formally the Communion with Rome. Mar Shimun XIII continued to be patriarch and his successors became leaders of the body now known as Assyrian Church of the East.
The Josephite line of Amid
The Chaldean Patriarchs based in Amid, now Diyarbakır, was started by Joseph I who in 1681 separated from the patriarchal See of Alqosh entering in Full Communion with Rome
- 98 Mar Joseph I (1681-1696)

- vacant (1827-1830)
At the death of Augustine Hindi this See remained vacant and in 1830 merged with the Alqosh line in the person of Mar Yohannan Hormizd, thus forming the modern Chaldean Catholic Church.
The Alqosh/Mosul line
The patriarchal See of Alqosh, known in the 17th-18th century also as Eliya line, was the oldest and largest patriarchal See of the Church of the East, the only one existing patriarchal line before the 1553 split, and traces itself back from St. Thomas in the 1st-century. In 1610 Mar Eliyya VIII (1591-1617), Patriarch of the See of Alqosh, entered communion with the Catholic Church. Eliyya VIII, however died in 1617 and his successor quickly repudiated the union.
In 1778, with the death of Eliya XII (or XI) Denkha, the See of Alqosh divided between Mar Eliyya XIII Isho-Yab, not in communion with Rome, and his cousin Mar Yohannan VIII Eliyya Hormizd, who professed to be Catholic. In 1804, with the death of Eliyya Isho-Yab, Yohannan Hormizd remained the only incumbent of this ancient See. He was recognized patriarch by Rome only in 1830, after the merging of the Chaldean see of Amid, thus forming the modern Chaldean Catholic Church.
