Abstract
This chapter aims to provide an outline of the archaeological remains reflecting the Ottoman presence on the Middle Nile, with preliminary interpretation and suggestions for areas in which future research could most profitably concentrate. The Nubian frontier region of the Ottoman Empire is one of its least-known areas. It raises numerous questions relating to both Sudanese and Ottoman history, as well as the nature of relations between the Ottomans and the Funj, in which the Ottoman garrisons on the Middle Nile must have played an intermediary role. While Sai is traditionally thought of as marking the southernmost extremity of Ottoman rule, the evidence of some of the sites above suggests that Ottoman rule extended further south, towards Hannek.
