Egyptian Conquest and Administration of Nubia
After the Second Intermediate Period (1730–1552 bce), the reconquest of Lower Nubia and the conquest of Upper Nubia by the Egyptian army happened in several phases during the New Kingdom, the powerful realm of Kush being supported by large African coalitions. Since the reign of Thutmose III (1458–1426 bce), the country being at last pacified, an administrative disposal was improved to exploit the resources of Nubia, whose knowledge increased until the death of Sety I. Rameses II (1279–1214 bce) was mostly interested in Lower Egypt where he built several temples devoted to the cult of his own sacred image but apparently less in Upper Nubia. After his reign, the interest of Egypt for the Nubian territories decreased along with its political and economic supremacy.
