 The reign of Yazdegerd II marks the start of a new inscription on the Sasanian coins; "mzdysn bgy kdy" ("The Mazda-worshipping majesty, the Kayanian"), which displays his fondness of the legendary Avestan dynasty, the Kayanians.This is due to a shift in the political perspective of the Sasanian Empire−originally disposed towards the West, was now changed to the East.This shift, which had already started under Yazdegerd I and Bahram V, reached its zenith under Yazdegerd II.
