Magadha Kingdom
It was an ancient kingdom of India, situated in what is now west-central Bihar state, in northeastern India. It was the nucleus of several larger kingdoms or empires between the 6th century BC and the 8th century AD.The early importance of Magadha may be explained by its strategic position in the Ganges River valley, enabling it to control communication and trade on the river. The river further provided a link between Magadha and the rich ports in the Ganges delta.
