This volume presents a series of articles adapted from those read at the 2019 workshop, held in Paris. entitled: "Bishops and Bishoprics in Egypt, Nubia, and Ethiopia (4th-13th centuries)." This collection thus aims to compare the processes of Christianization as well as the relative influences of the anti-Chalcedonian Patriarchate of Alexandria in the Christian institutions of medieval northeast Africa. Contributions explored not only the dynamics of the Alexandrian church in Egypt, but also the lesser-known developments of bishoprics in Nubia and Ethiopia. Regional differences were emphasized as were the relative powers of bishoprics over local governance. Moreover, this volume addresses gaps in our knowledge in the period of Late Antiquity, that is, in the 4th to 6th centuries. Taking an interdisciplinary approach, authors examine the bishoprics of Northeast Africa through the lens of archaeology, history, philology, as well as art history. The resulting volume not only redefines the interconnected Christianities of Egypt, Nubia, and Ethiopia, but also the tensions that informed its medieval character, including, but not limited to issues of local sovereignty as well as the patriarchal authority.
