Pushyamitra Shunga was a Brahmin who then took over the throne and established the Shunga dynasty. Buddhist records such as the Ashokavadana write that the assassination of Brihadrata and the rise of the Shunga empire led to a wave of persecution of Buddhists, and a resurgence of Hinduism. According to John Marshall, Pushyamitra Shunga may have been the main author of the persecutions, although later Shunga kings seem to have been more supportive of Buddhism. Other historians, such as Etienne Lamotte and Romila Thapar, partially support this view.
