Persians drive the Aksumites from Yemen
A small force of Khosrow I makes Yemen Iranian

Around 570 the Himyarite prince Sayf ibn Dhi Yazan won the help of Shah Khosrow I, and a Persian force under Wahriz defeated the Aksumites and took Sana'a. Yemen became a Sasanian vassal and, by the end of the century, a province ruled by Persian governors.
