Yohannes I (Ge'ez: ቀዳማዊ ዮሐንስ qädamawi yōḥānnis, Amh. qädamawi yōhānnis, also sometimes called John I), throne name A'ilaf Sagad (Ge'ez: አእላፍ ሰገድ a'ilāf sagad, "to whom tens of thousands bow"), (c. 1640 – 19 July 1682) was Emperor (nəgusä nägäst) (1667–1682) of Ethiopia, and a member of the Solomonic dynasty. He was the fourth son of Fasilides.
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 one 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.
