Prabhavati

Prabhavati was a 4th-century regent of the western Indian Vakataka dynasty. Prabhavati was the daughter of a Naga dynasty princess from northern India who had been made a consort of the Gupta emperor Chandragupta II when the Naga lands were overrun by Gupta soldiers. Recognized as an heiress of Chandragupta, Prabhavati was married to the Vakataka king as a diplomatic gift. When the Vakataka king died shortly after the wedding, Prabhavati took the reins of government and ruled for 20 years, allying the Vakataka state closely with Gupta interests.
