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.
Hormizd II
After his death, he was succeeded by his eldest son Adur Narseh, who, after a brief reign which lasted few months, was killed by some of the nobles of the empire. They then blinded the second, and imprisoned the third (Hormizd, who afterwards escaped to the Roman Empire). The throne was reserved for the unborn child of Hormizd II's wife Ifra Hormizd, which was Shapur II. It is said that Shapur II may have been the only king in history to be crowned "in utero", as the legend claims that the crown was placed upon his mother's womb while she was pregnant. However, according to Shahbazi, it is unlikely that Shapur was crowned as king while still in his mother's womb, since the nobles could not have known of his sex at that time. He further states that Shapur was born forty days after his father's death, and that the nobles killed Adur Narseh and crowned Shapur II in order to gain greater control of the empire, which they were able to do until Shapur II reached his majority at the age of 16.
