Bēlu-bāni, son of Adāsi, was the forty-eighth ruler of Aššur according to the Assyrian King List [/riao/kinglists/assyriankinglist/index.html] (AKL). He is said to have exercised kingship for ten years. Exactly how Bēlu-bāni came to power is uncertain because his own father's claim to power is unclear; Adāsi was either (1) one of six men (the so-called ṭuppišu-kings; Eder 2004, 209) who vied for the throne in the time of Aššur-dugul or (2) was the sixth and final eponym-official of Aššur-dugul (Reade 2001, 7). If the latter scenario proves to have been the case, then Bēlu-bāni, with the help of his father, may have seized the throne from his immediate predecessor Aššur-dugul. J. Reade (ibid.) proposes that Bēlu-bāni, Libāya, and Šarma-Adad I were either governors of Aššur who were dependant on the city Ekallātum or were independent rulers of Ekallātum and that those three men were contemporaries of Puzur-Sîn and Bāzāyu, both of whom sat on the Assyrian throne in Aššur; in this proposed scenario, Libāya and Šarma-Adad I, Bēlu-bāni's son and grandson respectively, would have been contemporaries of Bāzāyu, a second son of Bēlu-bāni. Whatever the case may be, Adāsi and his son Bēlu-bāni founded a new dynasty in Aššur that lasted many generations.
