In the decade following the sack, the Assyrian influence in Egypt quickly waned as Psamtik I managed not only to dominate the other kinglets of the Delta region but also freed himself from Assyrian vassalage. With Thebes' influence and outreach deeply weakened, Psamtik sent a strong military fleet to the city in 656 BC and immediately received its submission. To affirm his control over the city, he had his daughter Nitocris I adopted by Amenirdis II, who was not only the daughter of Taharqa but also the Divine Adoratrice of Amun, then the pinnacle of the powerful priesthood of Amun in the city.
