At the time of the death of Rudra Sena II, his two minor sons, were 5 and 2 years old respectively. Therefore, Prabhavati Gupta had to shoulder the responsibility of looking after the administration. In her work she must have been helped by his powerful partner, Chandra Gupta II. That is why copper plates of Prabhavati mention details of Gupta dynasty, along with the dynasties of Vakataka dynasty.

Some scholars are of the view that these copper plates were written by Gupta officers who lived in the kingdom of the Vakatakas. It is also said that Chandra Gupta had sent Kalidas to Vakataka kingdom to teach his grandsons-in-law. It is also said that Pravarsena II i.e. Damodar Sena had written a book named `Setubandhu` which was corrected or edited by Kalidas himself.

During the reign of Prabhavati Gupta, Chandra Gupta II had attacked and defeated the Sakas. As a result of the defeat of the Sakas the provinces of Gujrat and Kathiawar were also included in the Gupta Empire. In the said war with the sakas, prabhavati gupta must have helped his father.

During the regent ship of Prabhavati Gupta, Diwakar sena had died and the younger son Damodar Sena became the king on attaining the majority.
