Soon after his accession Skandagupta had to face the Hunas who had already proved themselves to be terror to both Europe and Asia. About the middle of the fifth century AD one branch of the Hunas known as White Hunas occupied the Oxus valley and threatened both Persia and India. They conquered Gandhara and threatened the very existence of the Gupta Empire. Skandagupta inflicted such a terrible defeat upon the Hunas that they dared not disturb the empire for nearly half a century. It was a magnificent achievement for which he assumed the title Vikramaditya in imitation of his grandfather. The ChandraVyakarana and Kathasaritsagara refer to Skandagupta's victory over the Hunas. His constant source of anxiety was the old Saka kingdom of Saurashtra newly annexed to the Gupta Empire where he appointed Parnadatta as governor. An inscription in the Girnar hill near Junagarh in Kathiawar refers to the restoration of the ancient embankment of the great Sudarsana Lake which had burst owing to heavy rains in the first year of Skandagupta's reign. Inspite of the Huna invasion and other troubles Skandagupta was able to maintain the mighty empire.

Harisena the court poet of Samudragupta lays special emphasis upon Samudragupta's learning and wisdom, sharp and polished intellect and above all his poetical and musical talents. He also refers to Samudragupta's charity and kindness even to conquered kings. The variety of gold coins issued by Samudragupta not only indicate the power, wealth and grandeur of his empire but also give us some idea of his appearance and insight into his personal qualities. The Guptas were followers of the Brahmanical religion and Samudragupta fully maintained the tradition of religious toleration.
