Under Chandragupta I (320-335), the empire was revived in the north. Like Chandragupta Maurya, he first conquered Magadha, set up his capital where the Mauryan capital had stood (Patna), and from this base consolidated a kingdom over the eastern portion of northern India. In addition, Chandragupta revived many of Ashoka's principles of government. It was his son, however, Samudragupta (335-376), and later his grandson, Chandragupta II (376-415), who extended the kingdom into an empire over the whole of the north and the western Deccan. Chandragupta II was the greatest of the Gupta kings; called Vikramaditya ("The Sun of Power"), he presided over the greatest cultural age in Classical India.
