Greater Magadha is a concept in studies of the early history of India.[1] It is used to refer to the political and cultural sphere that developed in the lower Gangetic plains during the Vedic age. The śramaṇa culture of Greater Magadha developed separately from the orthodox Brahmin-oriented śrauta culture to its west, that was characteristic of the upper Ganges basin (the Ganga-Yamuna doab).
