History of India, c. 150 A.D. to 350 A.D.: Naga–Vakataka Imperial Period c22.45

Thus from 272 up to 292, for 20 years, the Kushans got the protection of the Sassanian king and assumed the position of a vassal king. In that period the Bhāraśivas and after them Pravarasena I would have operated against the Kushans in India. After 293 A.D. they must have been more pressed by Prāvarasena, who may be regarded to have broken their power in India, whereon the Kúshánsháh shifted himself into Kabul. The Sassanians were hard-pressed by the Romans and could not be of assistance to the Kushans. The final suppression of the Kushans, who revived in 302-309, is to the credit of Samudra Gupta and Chandra Gupta II. There does not seem to be any room in history for a conquest of the Sassanians over North-West or Western India. That the Sassanian rule extended over Sistān is proved by their title SAKANSHAH and is confirmed by Kālidāsa who places the Pārasikas next to Sindh in the invasion of Raghu: sthala-vartmnā, through the Bolān Pass, as opposed to the sea-route from Aparānta to East Persia.
