 The expansion of the Sasanians in northwestern India, which put an end to the remnants of Kushan rule, may also have been done at the expense of the Western Satraps and the Satavahanas.Sindh coinage of Sasanian Empire rulers from Shapur II down to Peroz I are known, covering approximately the period from 325 to 480 CE.The last coins of the series, those copied on Peroz I (r. 459-484), deviate from the series as they introduce a Brahmi legend, often with the title "Rana Datasatya".
