Magadha (IPA: [məɡəd̪ʰaː]) was a region and kingdom in ancient India, based in the eastern Ganges Plain. It was one of the sixteen Mahajanapadas during the Second Urbanization period. The region was ruled by several dynasties, which overshadowed, conquered, and incorporated the other Mahajanapadas. Magadha played an important role in the development of Jainism and Buddhism and formed the core of the Haryankan Empire, Nanda Empire, Mauryan Empire, Shunga Empire and Gupta Empire.
