With both empires preoccupied by these threats, a largely peaceful period followed, interrupted only by two brief wars, the first in 421–422 after Bahram V persecuted high-ranking Persian officials who had converted to Christianity, and the second in 440, when Yazdegerd II raided Roman Armenia.[50] ./cache/en-wikipedia-org-1866.html ./txt/en-wikipedia-org-1866.txt
