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.
