King of Assyria and Babylonia (726-722). He succeeded his father in the personal union of the thrones of Assyria and Babylonia. In the Babylonian King List A he is referred to as Ulūlāyu (a reference to his birth month and likely his former name), and in the Ptolemaic Canon as Ilulayos. He and his father form the “Dynasty of Baltil” (i.e. the city of Aššur) in the BKLA.
