The Ethiopian Empire (), also formerly known by the exonym Abyssinia (derived from the Arabic "al-Habash"), or just simply known as Ethiopia (; Amharic and Tigrinya: ኢትዮጵያ , , Oromo: Itoophiyaa, Somali: Itoobiya, Afar: "Itiyoophiyaa"), was a monarchy that spanned a geographical area in the current states of Ethiopia and Eritrea. It began with the establishment of the Solomonic dynasty by Yekuno Amlak from approximately 1270 and lasted until 1974, when Emperor Haile Selassie was overthrown in a coup d'état by the communist Derg. It was throughout much of its existence surrounded by hostile forces in the African Horn however it managed to preserve and develop its ancient form of Christianity based kingdom.
