Piye or also known as Piankhithe Ku sh ite ruler of Nubia.
Nubia had been a vassal of early Egypt for approximately 2,500 years by the perIod of Piye's takeovers. All this while Nubia's culture was accepting and familiarizing to the well-known Egyptian culture. In the late 8th century BC, when Pi ye rose to power, Egypt as a realm had finished and the civilization was much run-down and separated in governance. Essentially Nubia was ever waiting and viewing for their chance to rise, and Pi ye must have seen himself as satisfying the ready moment. Lastly, he led the Nubians against their once long time overlords and now the tables were turned. This measured himself the true ruler of Egypt as well, the correct successor to the transcendent traditions experienced by the Pharaohs such as Ramses II and Thutmose III.
