Middle Egypt is the section of land between Lower Egypt and Upper Egypt, stretching upstream from Asyut in the south to Memphis in the north. At the time, Ancient Egypt was divided into Lower and Upper Egypt, though Middle Egypt was technically a subdivision of Upper Egypt. It was not until the 19th century that archaeologists felt the need to divide Upper Egypt in two. As a result, they coined the term "Middle Egypt" for the stretch of river between Cairo and the Qena Bend. It was also associated with a region termed "Heptanomis", generally as the district which separates the Thebaïd from the Delta.
