He appears to have succeeded his father Adityavarman on the weakened Chalukya throne, in the period following the death of his grandfather Pulakeshin II.
[1] After Pulakeshin II was defeated and probably killed during a Pallava invasion in 642–643 CE, Adityavarman appears to have held the weakened Chalukya throne, as attested by the Kurnool (Karnul) grant inscription.
The inscription first praises the foot of the Hindu god Hari (Vishnu) that crushed the demon (Bali), followed by a prashasti (eulogy) of the Chalukya dynasty.
The genealogy portion of the prashasti mentions Abhinavaditya, his father Adityavarman, and his grandfather Pulakeshin II; all three kings are accorded the imperial titles Maharajadhiraja and Parameshvara.
[7] Next, the inscription records Abhinavaditya's grant of the Nelkunda village, located in the Uchcha-shringa vishaya (district) to a Brahmana named Kuppa-sharman.
