Malwa Plateau in the context of "Maurya"

The Maurya Empire was a geographically extensive Iron Age historical power in South Asia with its power base in Magadha. Founded by Chandragupta Maurya around c. 320 BCE, it existed in loose-knit fashion until 185 BCE. The primary sources for the written records of the Mauryan times are partial records of the lost history of Megasthenes in Roman texts of several centuries later; and the Edicts of Ashoka. Archaeologically, the period of Mauryan rule in South Asia falls into the era of Northern Black Polished Ware (NBPW).

Through military conquests and diplomatic treaties, Chandragupta Maurya defeated the Nanda dynasty and extended his suzerainty as far westward as Afghanistan below the Hindu Kush and as far south as the northern Deccan; however, beyond the core Magadha area, the prevailing levels of technology and infrastructure limited how deeply his rule could penetrate society. During the rule of Chandragupta's grandson, Ashoka (ca. 268–232 BCE), the empire briefly controlled the major urban hubs and arteries of the subcontinent excepting the deep south. The Mauryan capital (what is today Patna) was located in Magadha; the other core regions were Taxila in the northwest; Ujjain in the Malwa Plateau; Kalinga on the Bay of Bengal coast; and the precious metal-rich lower Deccan Plateau. Outside the core regions, the empire's geographical extent was dependent on the loyalty of military commanders who controlled the armed cities scattered within it.
