Ashtat Yeztayar was an Iranian military officer under what last great king of the Sasanian Empire, reigning from 590 to 628?
Khosrow II Khosrow II (Chosroes II in classical sources; Middle Persian: "Husrō(y)"), entitled "Aparvēz" ("The Victorious"), also Khusraw Parvēz (New Persian: خسرو پرویز ), was the last great king of the Sasanian Empire, reigning from 590 to 628.
Ashur-uballit II Ashur-uballit II "(Aššur-uballiṭ II)" was the last king of the Neo-Assyrian Empire, succeeding Sin-shar-ishkun (623–612 BC). He took his name from Ashur-uballit I, the Assyrian king who had overthrown Mitanni Empire and defeated the Hittite Empire, and started the Middle Assyrian Empire (1365 BC–1020 BC). While it is clear that he was a member of the Assyrian royal family, and that he was a "tartan" (General) of the Assyrian army before declaring himself king, there is some disagreement as to whether or not he was the brother of Sin-shar-ishkun.
