Christianity reached Ethiopia during the reign of Emperor Ezana (c. 303–c. 350 CE) primarily through the influence of Saint Frumentius, a Syrian student from Tyre.12

Frumentius and his companion, Aedesius, were captured and brought to the court of the Aksumite kingdom, where they became civil servants. Frumentius eventually served as a tutor to the crown prince, Ezana, and was granted permission to evangelize and support visiting Christian merchants from the Roman Empire.12

The spread of the religion was facilitated by the existing presence of Greco-Roman merchant communities in the port of Adulis, which served as a gateway for Christianity from the eastern Mediterranean. After Frumentius was ordained as the first bishop of Aksum by St. Athanasius of Alexandria, he returned to Ethiopia to baptize King Ezana. Following this conversion, Christianity was established as the official state religion, strengthening political ties with the Byzantine Empire.3124
