In the east around 350 CE, Shapur II gained the upper hand against the Kushano-Sasanian Kingdom and took control of large territories in areas now known as Afghanistan and Pakistan, possibly as a consequence of the destruction of the Kushano-Sasanians by the Chionites. The Kushano-Sasanian still ruled in the north. Important finds of Sasanian coinage beyond the Indus river in the city of Taxila only start with the reigns of Shapur II (r. 309–379) and Shapur III (r. 383–388), suggesting that the expansion of Sasanian control beyond the Indus was the result of the wars of Shapur II "with the Chionites and Kushans" from 350 to 358 CE as described by Ammianus Marcellinus. During the last phase of the reign of Shapur II, a Sasanian mint was established south of the Hindu Kush, the role of which was probably to pay local troops. The Sasanians probably maintained control until Bactria fell to the Kidarites under their ruler Kidara around 360 CE,The Huns, Hyun Jin Kim, Routledge, 2015 p.50 sq and Kabulistan fell to the Alchon Huns circa 385 CE.
