Zakutu
Zakutu (l. c. 728 - c. 668 BCE) was the Akkadian name of Naqi’a, a secondary wife of Sennacherib of Assyria (r. 705-681 BCE). Though she was not Sennacherib’s queen, she bore him a son, Esarhaddon, who would succeed him. She may have ruled briefly as queen after Esarhaddon’s death and was grandmother to his successor, Ashurbanipal.
She is best known for the Zakutu Treaty which ensured a smooth transition of power after Esarhaddon (r. 681-669 BCE) died unexpectedly on campaign in Egypt. Ashurbanipal (r. 668-627 BCE) was able to assume the throne without challenge due primarily to his father’s careful planning and the claim that Zakutu was responsible for Ashurbanipal’s rise to power has been discredited. Her treaty only ensured that Esarhaddon’s wishes were honored by the court and nobility.
