Indo-Sasanians

The Indo-Sassanids, Kushano-Sassanids or Kushanshas (also Indo-Sassanians) were a branch of the Sassanid Persians who established their rule in the northwestern Indian subcontinent during the third and fourth centuries at the expense of the declining Kushans. They were in turn displaced in 410 by the invasions of the Huna people. They were able to re-establish some authority after the Sassanids destroyed the Hephthalites in 565, but their rule collapsed under Arab attacks in the mid 7th century.

History

First Indo-Sassanid period

The Sassanids, shortly after victory over the Parthians, extended their dominion into Bactria during the reign of Ardashir I around 230 CE, then further to the eastern parts of their empire in western Pakistan during the reign of his son Shapur I (240–270). Thus the Kushans lost their western territory (including Bactria and Gandhara) to the rule of Sassanid nobles named Kushanshahs or "Kings of the Kushans".

Around 325, Shapur II was directly in charge of the southern part of the territory, while in the north the Kushanshahs maintained their rule until the rise of the Kidarites.
