Ashur-uballit I (Aššur-uballiṭ I), who reigned between c. 1363 and c. 1328 BC, was the first king of the Middle Assyrian Empire. After his father Eriba-Adad I had broken half a century of intermittent Hurrian- Mitanni influence over Assyria, Ashur-uballit I's defeat of the Mitanni king Shuttarna III marks Assyria's full ascendancy over the Hurri-Mitanni Empire, much of which it annexed, and the beginning of its reemergence as a powerful empire. Later on, due to disorder in Babylonia following the death of the Kassite king Burnaburiash II, Ashur-uballit invaded and established Kurigalzu II on the Babylonian throne, in the first of what would become a series of Assyrian interventions in Babylonian affairs.
