Yohannan VIII Hormizd
Meanwhile, the Vatican reconsidered the condemnation of Yohannan Hormizd in the light of fresh information, and on 25 November 1826 publicly absolved him. At the same time, to restore the peace of the Chaldean Church, it urged the 66-year-old former patriarchal administrator to renounce his claims to the archdiocese of Mosul and to retire quietly. Yohannan, vindicated by the Vatican's absolution and supported by the local civil authorities, stubbornly refused to retire. Instead, he fought back against his opponents. In 1827, during the absence of the superior Gabriel Dambo in Rome, a number of monks in the monastery of Rabban Hormizd rebelled against its administrator Yohannan Gwera, who enjoyed the support of the metropolitan Joseph Audo. Yohannan Hormizd upheld the rebels, and was also able to have Basil Asmar expelled from Telkepe, forcing him to take refuge in Amid.
Hormuzan
Hormuzan is first mentioned in 609 as one of the Sasanian officers who participated in the battle of Dhi Qar. The rebelling Arabs managed to defeat the Sasanians at the battle, but order was soon restored by Ruzbi, the governor ("marzban") of al-Hira. In 628, Khosrow II was overthrown by his son Kavadh II, who crowned himself as the new "shahanshah" (king of kings) of the Sasanian Empire. Three days later, Kavadh ordered Mihr Hormozd to execute his father. In 632, after a period of coups and revolts, Yazdegerd III (r. 632–651) was crowned as king of the Sasanian Empire at Estakhr, an ancient Iranian city in Pars, where the Sasanian family had founded their empire.
