Early Historical Period : Haryankas, Ajatasatru
(495-462 bc) By embarking upon a policy of conquest, he declared war against Prasenjit of Kosala, who was his maternal uncle. His success against a powerful confederacy of 36 kingdoms and republican states under the leadership of Lichchhavis of Vaisali, is indeed, remarkable. The conflict continued for about 15 years and finally he succeeded in subduing the opponents including the Lichchhavis. Like his father Binbisara, it is not clearly known whether he was a follower of either Jainism or Buddhism, since the religious texts of both the religions equally claim that he was a follower of their faiths. It is generally believed that in the beginning, he was a follower of Jainism. But subsequently, he changed his mind and embraced Buddhism. It is said that he interviewed Lord Buddha and confessed his guilt with regard to killing his father Bimbisara. In fact, his meeting with Gautama Buddha is indicated in one of the sculptures of Bharhut.
SUCCESSORS OF AJATASATRU
According to the Jaina and Buddhist texts, several successors of Ajatasatru ruled Magadha for about 166 years. Unfortunately, most of them were non-entities. However, among them we come to know about one ruler named Udayin.
