602 - 628 PERSIAN CAMPAIGN - KHOSROE (Khosrow)II (King of Persia)
Attacked the leader of Byzantium at the time Phocas ( r.602-610) trying to get as much territory as possible. He promised the Jews lead by the Exilarch Nehemia ben Hushiel, that if they would attack Eretz- Israel he would allow them back in their homeland. Heraclius (610-641), overthrew Phocas, and succeeded for a time in re-conquering all of Western Asia and some of Egypt. In 628 Khosroe was assassinated.
