v1.c36.65

58-57 Traditionally ascribed to a king Vikramāditya of Ujjain who is said to have expelled the Śakas from India. The tradition may have some historical foundation, but in any case it seems probable that the supposed founder of the era has been confused with Chandragupta II, Vikramāditya (380-414 A.D.), who finally crushed the Śaka power in Western India (the Western Satraps) (pp. 533-4). It seems more likely that the era marks the establishment of the Śaka supremacy by Azes I (p. 571), and that its use was transmitted to posterity by the Mālavas and other peoples who had once been the feudatories of the Śakas (p. 533).
