Turco-Egyptian conquest of Sudan (1820–1824)

The Turco-Egyptian conquest of Sudan was a major military and technical feat. Fewer than 10,000 men set off from Egypt, but, with some local assistance, they were able to penetrate 1,500 km up the Nile River to the frontiers of Ethiopia, giving Egypt an empire as large as Western Europe.
