Abuna Atnatewos II (Athanasius) was an Egyptian Coptic who served as the Abuna or head of the Ethiopian Orthodox Tewahedo Church (1869–1876). Originally a Coptic bishop from Egypt, he was brought to Ethiopia by Emperor Yohannes IV, who raised the $20,000 to pay Cyril V, Pope of the Coptic Orthodox Church. Abuna Atnatewos actively worked against the influence of Catholic missionaries; Asseggahen wrote to Antoine Thomson d'Abbadie that Atnatewos anathematized the Catholic bishop Massaia, and threatened to excommunicate the inhabitants of Shewa were they to associate with him.
