Chosroes II

Chosroes II. succeeded to the Persian throne in 591 A.D. on the deposition of his father Hormidas, of whose murder he was suspected. Expelled by his subjects on account of his cruelty he sought the aid of Mauricius, the Roman Emperor at Byzantium, and by his aid was restored. When Phocas dethroned and killed Mauricius, Chosroes, under the pretext of avenging his death, marched, in 604, with a large force into Asia Minor, and extended his conquests as far as Carthage. In 622 he was defeated and forced back into his own dominions by Heraclius. Five years later he was deposed and put to death by his son Sirves.
