Ge'ez language
Ge'ez literature is considered to begin with the adoption of Christianity in Ethiopia and Eritrea, as well as the civilization of Axum in the 4th century BCE during the reign of Ezana. While Ge'ez today is extinct and only used for liturgical purposes in the Eritrean Orthodox Tewahedo Church and Ethiopian Orthodox Tewahedo Church. Ge'ez language is ancestral to Tigre and Tigrinya languages.
