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.
Mar Ukba
Mar Ukba, an exilarch at Baghdad in the first half of the tenth century; the second exilarch to die in banishment. When Kohen Ẓedeḳ II was appointed "gaon" of Pumbedita he became involved in a controversy with Mar 'Uḳba over the revenues from Khorasan; and the "calif" Al-Muḳtadir (908-932) was induced by Ẓedeḳ's friends to depose Mar 'Uḳba. Soon afterward (917) the latter left Baghdad for Karmisin (Kermanshah), but when the young "calif" went for the summer to his palace at Safran, Mar 'Uḳba devised a scheme to win the royal favor by meeting Al-Muḳtadir's secretary daily in his gardens and greeting him with the recitation of beautiful verses. These pleased the calif's secretary so much that he wrote them down and showed them to his master, who in his turn was so delighted that he sent for Mar 'Uḳba, entered into conversation with him, and asked him to express a wish, whereupon the "gaon" requested that he might be reinstated. The "calif" granted this wish, and Mar 'Uḳba soon returned to Baghdad as exilarch. Kohen Ẓedeḳ and his friends, however, again succeeded in securing his deposition and banishment from the country, whereupon he went to Africa, and was received with high honors at Kairwan as a descendant of the royal house. A sort of throne ("bimah") was built for him in the synagogue, near the Ark of the Law, and he was always the third to read the "parashah," the scroll of the Law being brought to him in his seat.
