Libāya was the forty-ninth ruler of Aššur according to the Assyrian King List [/riao/KingLists/AssyrianKingList/AssyrianKingList/index.html#BelubaniDynasty] (AKL). After succeeding his father Bēlu-bāni, Libāya held power for seventeen years; he was followed on the throne by his son Šarma-Adad I. J. Reade suggests that Libāya and his son, like his father Bēlu-bāni, may have been either independent rulers of the city Ekallātum or were governors of Aššur who were dependant on the more powerful Ekallātum; thus, Libāya and Šarma-Adad I may have been contemporaries of Bāzāyu, a man whom the AKL states was a son of Bēlu-bāni who exercised kingship for twenty-eight years.
