First, the region of Aryavarta pertains to northern India, whereas the dominions of the Vakatakas were strictly speaking located in the Dakshinapatha or Deccan.
Finally, if Rudrasena had been killed by Samudragupta, it would be extremely unlikely that his son Prthivishena would accept a Gupta princess (Prabhavatigupta) as his daughter-in-law.
[4] Unlike his illustrious father Pravarasena, Rudrasena never assumed the imperial title of Samrāṭ and was instead referred to only as Mahārāja.
[5] The capital of Rudrasena's kingdom was Nandivardhana, which is probably identical to Nagardhan near Ramtek, about 13 miles north of Nagpur.
[7] The records of the Vakataka dynasty assert that their family's treasury, army, and prestige were "continuously on the increase" for 100 years at the time when Prithvishena I (the son and successor of Rudrasena) ascended the throne, which suggests that the reign of Rudrasena saw the continued maintenance of Vakataka power and influence.
