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 of Sakastan
Hormizd of Sakastan was a Sasanian prince who was the leader of a revolt in Sakastan and its surrounding regions. He was the son of Shapur Mishanshah, a Sasanian prince who governed Maishan, and was the son of the Sassanian shah Shapur I. Hormizd's mother was a certain queen named Denag. Hormizd had many other siblings named Hormizdag, Odabakht, Bahram, Shapur, Peroz, and Shapurdukhtak. In 260, his father died and was probably succeeded by Denag as the governor of Maishan. In 271, he was appointed as the governor of Sakastan and its surrounding regions. Three years later, when his cousin Bahram II ascended the throne, Hormizd's sister Shapurdukhtak married the latter. In ca. 281, Hormizd revolted against Bahram II, and was supported by the inhabitants of Eastern Iran, including the inhabitants of Gilan. Hormizd's revolt was finally suppressed in 283, and he was shortly executed under the orders of Bahram II, who appointed his own son Bahram III as the governor of Sakastan.
