The Kushite era of rule in Nubia was established after the Late Bronze Age collapse and the disintegration of the New Kingdom of Egypt. Kush was centered at Napata (now modern Karima, Sudan) during its early phase. After Kashta ("the Kushite") invaded Egypt in the 8th century BC, the monarchs of Kush were also the pharaohs of the Twenty-fifth Dynasty of Egypt, until they were defeated by the Neo-Assyrian Empire under the rule of Ashurbanipal a century later and finally expelled from Egypt by Psamtik I.
