Chandragupta II was succeeded by his second son Kumaragupta I, born of "Mahadevi" Dhruvasvamini. Kumaragupta I assumed the title, "Mahendraditya". He ruled until 455. Towards the end of his reign a tribe in the Narmada valley, the Pushyamitras, rose in power to threaten the empire. The Kidarites as well probably confronted the Gupta Empire towards the end of the rule of Kumaragupta I, as his son Skandagupta mentions in the Bhitari pillar inscription his efforts at reshaping a country in disarray, through reorganisation and military victories over the Pushyamitras and the Hunas.
