Ezana ; Ancient Greek: Ἠεζάνα, Aezana) was the ruler of the Kingdom of Aksum. One of the best-documented rulers of Aksum, Ezana is important as he first adopted for his country the religion of Christianity and the name of Ethiopia. Tradition states that Ezana succeeded his father Ella Amida (Ousanas) as king while still a child; his mother, Sofya, served as regent until he came of age.
