Butuga II (938–961 CE) became the ruler of the Western Ganga Dynasty after his elder brother Rachamalla III.
In order to ascend the throne he had to first seek help from the Rashtrakutas who were hitherto their arch enemies.
This helped forge a strong relationship between the Gangas and the Rashtrakutas, an alliance that lasted till the end of both kingdoms.
As a Rashtrakuta feudatory, he not only ruled Gangavadi but also many areas in the Malaprabha River basin and the Krishna River-Tungabhadra doab.
He is said to have a defeated a Buddhist scholar in a religious discourse and the Kudlur record speaks of him as a noted poet.
