The Third Intermediate Period of Ancient Egypt begins with the death of Pharaoh Ramesses XI in 1070 BC, ending the New Kingdom, and ends with the start of the Late period, for which various points are offered, though it is most often regarded as dating from the foundation of the Twenty-Sixth Dynasty by Psamtik I in 664 BC, following the expulsion of the Nubian rulers of the Twenty-Fifth Dynasty by the Assyrians under King Assurbanipal.
