Yohannan VIII Hormizd
Mar 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 Chaldean Church. After succeeding his uncle Eliya XII Denha in 1780 as patriarch of Mosul, he made a Catholic profession of faith and was recognised in 1783 by the Vatican as patriarchal administrator and archbishop of Mosul. His career as patriarchal administrator was controversial, and was marked by a series of conflicts with his own bishops and also with the Vatican. Suspended from his functions in 1812 and again in 1818, he was reinstated by the Vatican in 1828. In 1830, following the death of the Amid patriarchal administrator Augustine Hindi, he was recognised by the Vatican as "patriarch of Babylon of the Chaldeans" and the Mosul and Amid patriarchates were united under his leadership. This event marked the birth of the since unbroken patriarchal line of the Chaldean Catholic Church. Yohannan Hormizd died in 1838 and his successor Nicholas I Zaya was chosen by the Vatican, ending the centuries-old practice of hereditary succession in the Eliya line of the Church of the East.
Hormuzan
Hormuzan managed to survive, and along with Nakhiragan, Mihran Razi and Piruz Khosrow, including the rest of the survivors, regrouped at Bavel (Babylon), where they tried to repel the Arab army, but were once again defeated. Hormuzan then fled to Hormizd-Ardashir in Khuzestan, which he used as his base in his raids in Meshan against the Arabs. Yazdegerd III supported him in these raids, and believed that it was possible to regain the territories which had been taken by the Arabs. Hormuzan, along with the rest of the survivors of al-Qadisiyyah, later regrouped again and fought the Arabs at the battle of Jalula in 637. The Sasanian army was once again defeated and Mihran Razi was killed. Hormuzan then withdrew once again to Hormizd-Ardashir, where he chose to stay in case the Arabs should invade his domains.
