Explanation:
Brihadrata was assassinated in 185 BCE during a military parade, by the commander-in-chief of his guard, the Brahmin general Pusyamitra Sunga, who then took over the throne and established the Sunga dynasty. Brihadrata, the last ruler of the Mauryan dynasty, held territories that had shrunk considerably from the time of emperor Ashoka, although he still upheld the Buddhist faith.
