Around the middle of the 6th century CE, the Alchons, after having extensively invaded the heartland of India, had withdrawn from Kashmir, Punjab and Gandhara, and going back west across the Khyber pass they resettled in Kabulistan. It seems that there was a direct confrontation between the Alchon Toramana II and the Nezaks in Kabulistan, as he made overstrikes of Nezak coins, and at the same time adopted the Nezak bull's head in his own crown in some of his coins minted in Gandhara.
