Magadha was an ancient kingdom located on the Indo-Gangetic plains in eastern India and spread over what is today the modern state of Bihar. At the height of its power, it claimed suzerainty over the entire eastern part of the country (roughly the area of England) and ruled from its capital at Pataliputra (modern Patna, Bihar).
