c8.s1.t4.5

The causes of the abrupt dialectal shift from east to west undoubtedly lie in political and historical developments, that is, the decline of Magadha as the center of power in northern India after the collapse of the Mauryan empire and the movement of the center of political power in the following centuries toward the west and northwest.¹⁹ Like the eastern dialect under Aśoka, the central-western dialect of the post-Mauryan era was used far beyond what must have been its original homeland. Thus we find inscriptions in this standard epigraphic Prakrit as far afield as Orissa in the east, for instance, in the Hāthīgumphā inscription (SI I.213–21), while in the south it is abundantly attested in inscriptions from such sites as Nāgārjunakoṇḍa and Amarāvatī. This central-western MIA dialect was, in fact, virtually the sole language in epigraphic use in the period in question, and therefore seems, like Pāli, to have developed into something like a northern Indian lingua franca, at least for epigraphic purposes, in the last two centuries b.c.
