Spurred by threats from the south, Egypt’s New Kingdom pharaohs mounted military campaigns against Nubia, and by the Reign of Thutmose III (1479–1425 BC) Egyptians controlled Nubia to the 4th cataract. An Egyptian govenor administered the country called Kush and ensured the flow of Nubian gold to Egypt. Nubia also contributed exotic products such as animal skins, ivory, and ebony as well as dates, cattle, and horses prized for their quality. Despite being required to send many rich resources to Egypt, Nubia prospered during this period. Many Egyptians settled in Nubia, and Nubians moved north to Egypt.
