The Kidarites, vassals of the Hephthalite Empire are known to have invaded Taxila in c. 450 CE. Though repelled by the Gupta Emperor Skandagupta, the city would not recover- probably on account of the strong Hunnic presence in the area, breakdown of trade as well as the three-way war between Persia, the Kidarite State, and the Huns in Western Gandhara.
