Yohannan VIII Hormizd
For the next eight years Yohannan Hormizd seemed to justify the hopes placed in him. He lived on amicable terms with the Catholic missionaries and devoted his energies to the conversion to Catholicism of the villages under his authority. In May 1790, on the advice of the missionaries, he consecrated his nephew Shemon metropolitan, and in August of the same year sent him to the Zibar district, where he converted the Nestorian villages of Arena and Barzane. The following year he sent Shemon to Mengesh in the Sapna district, where he was equally successful. The high point of this honeymoon period came in February 1791, when the Vatican appointed him patriarchal administrator of the Amid patriarchate, recalling Lazar Hindi to Rome to leave him a free hand. This appointment led to strenuous protests from Lazar Hindi, his vicar-general Joseph Attar and the clergy of Amid, and on 3 February 1793 Yohannan Hormizd's appointment was rescinded.
Sasanian civil war of 589-591
Bahram Chobin, infuriated by Hormizd's actions, responded by rebelling, and due to his noble status and great military knowledge, he was joined by his soldiers and many others. He then appointed a new governor for Khorasan, and afterwards set for Ctesiphon, the capital of the Sasanian Empire. Meanwhile, Hormizd tried to come to terms with Vistahm and Vinduyih, "who equally hated Hormozd". Hormizd shortly had Vinduyih imprisoned, while Vistahm managed to flee from the court. After a short period of time, a palace coup under the two brothers occurred in Ctesiphon, which resulted in the blinding of Hormizd and the accession of the latter's son Khosrow II (who was their nephew through his mother's side). The two brothers had Hormizd killed shortly afterward. Nevertheless, Bahram continued his march to Ctesiphon.
