|Successor||minor son, with his wife Vijaya-Bhattarika as regent|
|Dynasty||Chalukyas of Vatapi|
Chandraditya (IAST: Candrāditya, r. c. 646-649 CE) was a king of the Chalukya dynasty of Vatapi that ruled in the Deccan region of south India. His father Pulakeshin II was a powerful emperor, who was defeated and most probably killed during a Pallava invasion.
Chandraditya was probably among the kings who held the weakened throne for a brief period after Pulakeshin's death, having been preceded by his brother Adityavarman, and Adityavarman's son Abhinavaditya. After his death, his wife Vijaya-Bhattarika appears to have ruled as a regent on behalf of their minor son. During this period, his brother Vikramaditya I, who later ascended the throne, seems to have restored the Chalukya power as the supreme commander of the Chalukya army.
Chandraditya is known from the Nerur and Kochre (or Kochri) grant inscriptions of his wife Vijaya-Bhattarika (alias Vijaya-Mahadevi). He also finds a mention in the Kuknur inscription of his younger brother Vikramaditya I.
Chandraditya was one of the sons of the powerful Chalukya king Pulakeshin II, who was defeated and probably killed during the Pallava invasion of the Chalukya capital Vatapi around c. 642 CE. The Chalukya power was restored by Pulakeshin's son Vikramaditya I around c. 655 CE, and the Chalukya history during the intervening period is uncertain: it is possible that after Pulakeshin's death, his son Adityavarman held the throne, followed by Adityavarman's son Abhinavaditya.
The Kuknur inscription of Vikramaditya accords Chandraditya the title Bhattaraka. The royal genealogy section of the Nerur inscription introduces Chandraditya's younger brother Vikramaditya I after his father Pulakeshin II, describing Vikramaditya as the restorer of the Chalukya rule. Therefore, scholars such as J. F. Fleet and D. C. Sircar theorize that Chandraditya was a feudatory ruler.
Other scholars, such as D. P. Dikshit, theorize that Chandraditya held the throne after Abhinavaditya, during c. 646-649 CE, based on the following points:
The inscriptions are dated in the regnal years of Vijaya-Bhattarika, which suggests that Chandraditya was dead when these grants were issued. According to one theory, his wife was ruling as a regent on behalf of their minor son at this time. It is possible that Vikramaditya rose to prominence during this period, and became the de facto ruler, after having restored the dynasty's power as the supreme commander of the Chalukya army. Later, he formally ascended the Chalukya throne, possibly after the son of Chandraditya and Vijaya died (naturally or otherwise).
