Islamic networks played a critical role in the regional integration of the Ethiopian highlands to the Red Sea basin, after the eighth-century collapse of the kingdom of Axum. However, the history of Ethiopia’s earliest Islamic settlements is still poorly known. Knowledge has increased over the last two decades, with the identification of several Islamic sites with the help of the local Muslim communities’ memory. In 2018‑2019, a cluster of several ancient Muslim cemeteries was surveyed by a French-Ethiopian team in the area of Arra (eastern Tigray). The preliminary results of the survey of Tsomar, a Muslim cemetery in use in the late 13th century, are presented here. Since no excavations have yet taken place, the study is based on surface observation, drone zenithal views and the analysis of nine Arabic inscriptions found on the Tsomar site.
