One year later, the feudal families of the Sasanian Empire, who were tired of war against the Byzantines and Khosrow's oppressive policies, freed Khosrow's son Sheroe, who had been imprisoned by his own father. The feudal families included: Shahrbaraz himself, who represented the Mihran family; the House of Ispahbudhan represented by "spahbed" Farrukh Hormizd and his two sons Rostam Farrokhzad and Farrukhzad; the Armenian faction represented by Varaztirots II Bagratuni; and finally the "kanarang" Kanadbak. In February, Sheroe, along with Aspad Gushnasp, captured Ctesiphon and imprisoned Khosrow II. Sheroe then proclaimed himself as king of the Sasanian Empire on 25 February, assuming the regnal name of Kavadh II. With the aid of Piruz Khosrow, he executed all his brothers and half-brothers, including Khosrow II's favorite son Mardanshah. Three days later, he ordered Mihr Hormozd to execute his father. With the agreement of the nobles of the Sasanian empire, Kavad II then made peace with the Byzantine emperor Heraclius; under the terms of this peace, the Byzantines regained all their lost territories, their captured soldiers, a war indemnity, along with the True Cross and other relics that were lost in Jerusalem in 614.
