Ancient History / Pre-Mauryan Era

Rise of Magadha Empire


    The factors that were responsible for the rise of Magadha Empire are both external and internal. Magadha kingdom was surrounded by three rivers, Son, Champa and Ganga on the three sides, so the enemies could not attack it easily. It had huge population, so it could easily employ them into its army. All the dynasties of Magadha were following the expansion policy. To its fortune, very strong and able monarchs ascended its throne continuously.



    Magadha empire was ruled by 3 strong dynasties namely, the Haryanka dynasty, the Sisunaga dynasty and the Nanda dynasty and later it was ruled by the Mauryan dynasty.

    • Ajatashatru has taken over forcefully the Magadha empire from his father Bimbisara and imprisoned him. He is said to be the inventor of two weapons that were used in wars. These weapons are Mahshilakantaka (weapon to throw big stones) and Rathamusala (blade chariot). He conquered Kosala, Malla and Vajji kingdoms. Ajatashatru's son Udayin, who built Pataliputra, came to power after him.
