The Rise of Magadha

Magadha embeds the districts of Patna and Gaya of the south Bihar.  The rivers of Ganges on the north, Son on the west, Champa on the east, the mountain Vindhya on the west embraced Magadha.  From the capital city of Girivrija, Haryanka dynasty ruled Magadha, but the history commences with the ascension of Bimbasara.  The earlier dynasty, the Brihadratas (founded by Jarasandha's father, the son of Vasu) ended when Pradyota asserted the throne of Avanti. The latter was a contemporary of the Buddha.
