مملكة حمير
In the late sixth century, Sasanian Empire of Persia and the Ethiopia-based Axumite Empire fought a series of wars over control of the Himyarite Kingdom in Yemen, Southern Arabia. After the Battle of Hadhramaut and the Siege of Sana'a in 570, the Aksumites were expelled from the Arabian peninsula. They had re-established their power there by 575 or 578, when another Persian army invaded Yemen and re-established the deposed king on his throne as their client. It marked the end of Ethiopian rule in Arabia.
