Yohannes I (), also known as Yohannes the Righteous (Ge'ez: ጻድቁ ዮሐንስ), throne name A'ilaf Sagad (Ge'ez: አእላፍ ሰገድ; 1640 – 19 July 1682) was Emperor of Ethiopia from 1667 to 1682, and a member of the Solomonic dynasty. He was the fourth son of Fasilides. 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. Ancestry Of Amhara descent, Yohannes was the eldest son of Emperor Fasilides and succeeded him 1662. Reign According to G.W.B. Huntingford, Yohannes spent much of his reign campaigning, stating that 6 of the 11 itineraries he reproduces were military expeditions. Three of these were against the Agaw in Gojjam, and Agawmeder, one against the Oromo, and two punitive expeditions to the area around Mount Ashgwagwa—Angot and Lasta—to quash the revolts of Feres (in 1677) and Za Maryam (1679).

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.
