The Vayu Purana mentions that the Brihadrath dynasty was taken over by the Pradyota dynasty, which ruled Magadha for 138 years. The time assigned to Pradyota dynasty is approximately 800 – 682 BC. The Pradyota dynasty is mentioned in Buddhist and Jaina texts as well. They write that the Pradyota dynasty kings used to kill their fathers as a tradition to become kings. So patricide was common in Magadha.
