Early inscriptions in Ge'ez and Ge'ez script have been dated to as early as the 5th century BC, and in a sort of proto-Ge'ez written in ESA since the 9th century BC. Ge'ez literature begins with the Christianization of Ethiopia (and the civilization of Axum) in the 4th century, during the reign of Ezana of Axum.
