High Quality Content by WIKIPEDIA articles! The Magadha empire was established very likely by semi-mythical king Jarasandha who was, as it stated in the Puranas, a son of Brihadratha, one of the descendants of eponymical Puru. Jarasandha appears in the Mahabharatha as the "Magadhan Emperor who rules all India" and meets with an unceremonious ending. His descendants, according to the Vayu Purana, ruled Magadha for 1000 years followed by the Pradyota dynasty which ruled for 138 years. However, no sufficient evidence to prove the historicity of this claim. However, these rulers are mentioned in the Hindu texts, Buddhist texts and Jaina texts.
