Psamtik reunified Egypt in his ninth reignal year when he dispatched a powerful naval fleet in March 656 BC to Thebes and compelled the existing God's Wife of Amun at Thebes, Shepenupet II, daughter of the former Kushite Pharaoh Piye, to adopt his daughter Nitocris I as her heiress in the so-called Adoption Stela.
