Ashur-uballit I (Aššur-uballiṭ I), who reigned between 1365 and 1330 BC, was the first king of the Middle Assyrian Empire (1365–1050 BC). After his father Eriba-Adad I (1392-1366 BC) had broken Mitanni influence over Assyria, Ashur-uballit I's defeat of the Mitanni king Shuttarna II marks Assyria's ascendancy over the Hurri-Mitanni Empire, and the beginning of its emergence as a powerful empire. Later on, due to disorder in Babylonia following the death of the Kassite king Burnaburiash II, Ashur-uballit established Kurigalzu II on the Babylonian throne, in the first of what would become a series of Assyrian interventions in Babylonian affairs.
