Frumentius was a 4th-century Phoenician missionary who served as the first bishop of Aksum. Born in Tyre, he and his brother were taken as slaves to the Kingdom of Aksum following a shipwreck. After gaining the trust of the royal court, he helped educate the young heir, Ezana, and utilized his position to introduce Christian teachings to the region. He eventually traveled to Alexandria to seek formal ecclesiastical support, leading to his consecration as bishop and the establishment of the Ethiopian Church.
