The coins of Buddhagupta also reflect the process of decline that had set
in the Gupta empire. His gold coins are very rare. All these instances go to
prove that the process of enfeeblement of the empire had gone too far owing
to internal weakness and the war of succession that engulfed the Gupta
empire after Skandagupta’s exit.
     The death of Buddhagupta was followed by a confused period of internal
dissensions leading to the dismemberment of the empire and the renewed
invasion of the Hunas. According to official genealogy Buddhagupta’s
brother, Narasimhagupta, occupied the imperial throne, and was followed by
his son and grandson. The reigns of these three emperors covered the first
half of the sixth century AD.
     But it was during this period that we find the existence of two other kings
—Vainyagupta (AD 506) ruling in Samatata and Nalanda and Bhanugupta (AD
510–511) in Eran (Saugar district, Madhya Pradesh). Vainyagupta’s gold
coins and seals leave no doubt that he belonged to the imperial Gupta family.
It is probable that Vainyagupta was at first appointed a provincial governor of
Bengal by Buddhagupta and then he ascended the imperial throne in AD 506.
The other, Bhanugupta, known from a single inscription of Eran, fought a
famous battle in which his general Goparaja died and his wife committed
sati. The battle fought at Eran must have been directed against the Huna
chief, Toramana, who had by that time conquered this region. But
unfortunately, the result of the battle is not known and Bhanugupta remains a
shadowy figure.
     Vishnugupta was the last ruler of the imperial Gupta family which had
enjoyed sovereignty for more than 230 years.
