The Indian subcontinent was dominated by the Imperial Guptas and the Vakatakas for some two and a half centuries beginning mid-third century A.D. Numerous works on these dynasties have appeared in English and Hindi, specially on the Imperial Guptas. But a separate volume exclusively devoted to the study of their mutual relations has still been a desideratum. It has become an imperative in the light of recent epigraphically and numismatics finds. The author of this monograph has looked upon Vakataka - Gupta relations from the peep hole of literary sources as well which, if interpreted correctly, presents a very interesting pattern of their changing relationships. The present work is the first research monograph from an authoritative pen throwing light on this so far neglected aspect of ancient Indian history.
