In the Jātaka Commentary this is given as the name of numerous kings of Bārāṇasī. In most cases we are told nothing further of them than that they reigned at Bārāṇasī at the time of the incidents related in the story. Brahmadatta, was probably the dynastic name of the kings of Bārāṇasī. Thus, for instance, in the Gaṅgamāla Jātaka (J.iii.452) Udaya, king of Bārāṇasī, is addressed as Brahmadatta.

In the Gaṇḍatindu Jātaka (J.v.102-106) however, Pañcāla, king of Uttarapañcāla, is also called Brahmadatta; in this case it was evidently his personal name. It was also the name of the husband of Piṅgiyāni (q.v.) He was a king, but we are not told of what country. He is identified (J.v.444) with Kuṇāla.
