Chandragupta Maurya was the founder of the Maurya Empire, a geographically-extensive empire based in Magadha. He reigned from 320 BCE to 298 BCE. The Magadha kingdom expanded to become an empire that reached its peak under the reign of his grandson, Ashoka the Great, from 268 BCE to 231 BCE. The nature of the political formation that existed in Chandragupta's time is not certain. The Mauryan empire was a loose-knit one with large autonomous regions within its limits.
7th-century Bhadrabahu inscription at Shravanabelagola (Sanskrit, Purvahale Kannada script). This is the oldest inscription at the site, and it mentions Bhadrabahu and Prabhacandra. Lewis Rice and Digambara Jains interpret Prabhacandra to be Chandragupta Maurya, while others such as J F Fleet, V. R. Ramachandra Dikshitar, and Svetambara Jains state this interpretation is wrong.
Chandragupta's guru was Chanakya, with whom he studied as a child and with whose counsel he built the Empire. This image is a 1915 attempt at depicting Chanakya.
Chandragupta had defeated the remaining Macedonian satrapies in the northwest of the Indian subcontinent by 317 BCE.
