 The Nubian empire was Egypt’s historical enemy, with its territory spread throughout the areas of the second cataract, down into the area of Kush, and around the 4th and 5th cataracts around the area of Khartoum (Modern day Sudan).Around the time of the Second Intermediate Period Nubia seized land past its border with Egypt at the 1st cataract, almost wiping out Egypt’s empire.Egyptian Pharaoh Ahmose crushed the Nubian expansion and re-established Egyptian dominance by reunifying the empire while turning back the Nubians to the south.
