Brihadrata was the last ruler of the Indian Mauryan dynasty. He ruled c. 187–185 BCE. Maurya territories, centered around the capital of Pataliputra, had shrunk considerably from the time of the great Emperor Ashoka when Brihadrata came to the throne. He was killed in 185 BCE and power usurped by his commander-in-chief, the Brahmin general Pusyamitra Sunga, who then took over the throne and established the Sunga dynasty.
