Иоханнес I: Эфиопия императоры, діни даулар және Армян байланыстары

Emperor of Ethiopia from 1667 to 1682
Yohannes was appointed nəgusä nägäst by a council of the senior dignitaries of the Empire, at the encouragement of the noble Blattengeta Malka Krestos. The council then imprisoned the other sons of Fasilides on Mount Wehni, continuing the practice Fasilides had revived.

Of Amhara descent, Yohannes was the eldest son of Emperor Fasilides and succeeded him 1662.

Due to the violent religious controversy that Catholic missionaries had caused in Ethiopia under the reign of his grandfather Susenyos, Yohannes acted harshly towards Europeans. In 1669, he directed Gerazmach Mikael to expel all of the Catholics still living in Ethiopia; those who did not embrace the beliefs of the Ethiopian Church were exiled to Sennar. Six Franciscans sent by Pope Alexander VII to succeed in converting Ethiopia to Catholicism where the Jesuits had failed 30 years before, were executed during his reign. As a result, he favored Armenian visitors, whose beliefs also embraced Miaphysitism, and were in harmony with the Ethiopian Church. These included Khodja Murad, who undertook a number of diplomatic missions for the Emperor; and in 1679, the Emperor Yohannes received the Armenian bishop Yohannes, bearing a relic of Ewostatewos. The growing controversy over the nature of Christ had grown severe enough that in the last year of his reign Yohannes called a synod to resolve the dispute. The Ewostathian monks of Gojjam advocated the formula "Through Unction Christ the Son was consubstantial with the Father", by which they came to be known as the Qebat ("Unction") faction, who were supported by the Emperor's own son Iyasu; they were opposed by the monks of Debre Libanos, who at that time still advocated traditional Miaphysitism. The outcome of the synod is in dispute: according to E. A. Wallis Budge and H. Weld Blundell, Emperor Yohannes was convinced to condemn the Qebat doctrine, which led to Iyasu attempting to flee his father's realm; but according to Crummey, Yohannes favored the Gojjame delegation for political reasons: at the time Gojjam was an important province. These decisions were revisited once Iyasu became Emperor, at a synod he called in 1686.

Sources mentions only Sabla Wangel as the spouse of Emperor Yohannes I. She married Yohannes in October 1668 and likely gave birth to all (or almost allrefn|group=note|Only Eleni is uncertain. Sources mention Eleni as a daughter of Yohannes I, and sister of Iyasu I, but does not mention the mother. Nonetheless, the former empress is remembered as a ‘‘great patroness of literature’’ who was knowledgeable about theological books and supported the production of manuscripts. Sabla Wangel died on 13 January 1690 and was buried as a queen in the royal cemetery on the island of Mesrasha at Lake Tana alongside Yohannes I.
Tewoflos was his third son. Tewoflos reigned as Emperor between 1708 and 1711.
