The Mauryan Empire was divided into four provinces, with the imperial capital at Pataliputra, near the Ganges River in the modern state of Bihar in India. The Edicts of Ashoka, a collection of inscriptions made during Ashoka’s reign from 268-232 BCE, give the names of the Maurya Empire’s four provincial capitals: Tosali in the east, Ujjain in the west, Suvarnagiri in the south, and Taxila in the north.
