This book describes the broad network of studies which were involved in three years of archaeological research in the southern Tigray (Ethiopia), at the Mifsas Bäri site. The uniqueness of this work lies in the subject of our research and in the final results. Mifsas Bäri is the southernmost Late Aksumite (c. 550¿c. 700 CE) site known in Tigray, the ruins of which dominate the amazing landscape of Lake ¿ashenge. The data collected from the excavation, survey, pottery and anthropological analysis, historical and linguistic researches contribute to the knowledge of a region of southern Tigray during the so-called "Ethiopian dark age". This book offers to the scientific community and to scholars involved in the Ethiopian studies new, convincing results and information regarding a region and a period hitherto unknown in the history of ancient Ethiopia.
