Your list Just wanted to let you know the D mt period goes from ca 800 BC to the 5th 4th c BC when the proto Aksumite period starts The proto Aksumite period ends ca 1st c BC when the Aksumite period begins The date of Aksum s shift to the Zagwe dynasty which you forgot to include in the medieval list btw along with the Solomonic dynasty isn t known yet but it may actually be the 12th century since Anbessa Widim a king remembered by tradition to have been one of the last late Aksumite kings is now attested to ca 1125 1150 we have a colophon in a Bible written by the Patriarch Abba Mika el in 1150 which notes that Anbessa Widim was king when he was appointed in 1129 so the 937 date you have is much too precise and probably inaccurate It s based on the assumption that Gudit s reign was the beginning of the Zagwe dynasty and the end of Aksum which isn t necessarily the case Anyway happy editing Yom Ethiopia
