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Hindi, his vicar-general Joseph Attar and the clergy of Amid, and on 3 February 1793 Yohannan Hormizd's appointment was rescinded.
Hormizd III
The Arsacid ruler of Caucasian Albania, Vache II (), who was the nephew of the two brothers through his mother, and had been forced to convert to Zoroastrianism by Yazdegerd II, took advantage of the dispute by declaring independence and reverting to Christianity. Peroz later went to the domains of the Hephthalite monarch, who agreed to him support with soldiers in his struggle for the throne. In 459, Peroz, with Hephthalite and Mihranid assistance, led an army against Hormizd and defeated him. According to some sources, Hormizd was pardoned and spared by his brother. However, this is most likely a legend, which is disproved by other sources, that states Peroz had Hormizd and three members of his family killed. No coins minted during Hormizd's reign has been found.
