The second reign of Chosroes II., who is commonly known as Chosroes Eberwiz or Parwiz, lasted little short of thirty-seven years--from the summer of A.D. 591 to the February of A.D. 628. Externally considered, it is the most remarkable reign in the entire Sassanian series, embracing as it does the extremes of elevation and depression. Never at any other time did the Neo-Persian kingdom extend itself so far, or so distinguish itself by military achievements, as in the twenty years intervening between A.D. 602 and A.D. 622. Seldom was it brought so low as in the years immediately anterior and immediately subsequent to this space, in the earlier and in the later portions of the reign whose central period was so glorious. Victorious by the help of Rome, Chosroes began his second reign amid the scarcely disguised hostility of his subjects. So greatly did he mistrust their sentiments towards him that he begged and obtained of Maurice the support of a Roman bodyguard, to whom he committed the custody of his person. To the odium always attaching in the minds of a spirited people to the ruler whose yoke is imposed upon them by a foreign power, he added further the stain of a crime which is happily rare at all times, and of which (according to the general belief of his subjects) no Persian monarch had ever previously been guilty. It was in vain that he protested his innocence: the popular belief held him an accomplice in his father’s murder, and branded the young prince with the horrible name of “parricide.”
