Nubia

The Ta-Seti kingdom in Nubia to the south of Egypt was conquered by Egyptian rulers around 3100 BC, but by 2500 BC the Nubians had created a new kingdom further south, known as the Kingdom of Kush, centred on the upper Nile with a capital at Kerma. In the Egyptian New Kingdom period, Kush once more was conquered by Egypt. However, by 1100 BC a new kingdom of Kush had formed, with a capital at Napata. Nubian rulers conquered Egypt around 760 BC and retained control for about a century.
