Prince Peroz was born in 636, and was thus very young at the time of the reign of his father king Yazdegerd III and never exercised the imperial power of the Sasanians. According to the
Old Book of Tang, Peroz's father Yazdegerd III, requested military assistance from Tang China against the Arabs from 638 to 648, but each request was rejected by Emperor Taizong. In 654, Peroz sent envoys to the Tang Dynasty for aid, but was rejected by Emperor Gaozong. In 661, he again asked for military help. Emperor Gaozong dispatched a special envoy, Wang Mingyuan, to the Western Regions. Wang Mingyuan established the title
Governor of Persia with Peroz as chief governor (都督
Dudu) and ruling from
Jilingcheng (疾陵城) in what is now
Zaranj/
Zābol, on the modern border of Afghanistan and Iran, . 14 February 662, the Tang dynasty gave Peroz the title "King of Persia" (波斯王). In 663, the remaining Persian forces in Afghanistan were finally eliminated by the Rashidun Caliphate, Peroz and the rest of the imperial family, including his brother
Wahram escaped through the
Pamir Mountains in what is now
Tajikistan Between 670 and 674, Peroz arrived at the Tang court and was given the title of
Yòuwǔwèi Jīangjūn (右武衛將軍, "Martial General of the Right [Flank] Guards"). The
Emperor Gaozong of Tang allowed Sasanian refugees fleeing from the Arab invasion to settle in China. In 678,
Pei Xingjian, the
minister of personnel (吏部侍郎) of the Tang court, was ordered to escort Peroz back to Persia, with the main task of squelching an insurgency of the vassalized
Western Turkic Khan
Ashina Duzhi. Pei Xingjian got as far as
Suyab (in modern
Kyrgyzstan) and then fought successfully against Ashina Duzhi, before concerning the long distance to Persia thus leaving Peroz alone in the
Anxi Protectorate, and the Persian prince who was escorted back was Peroz's son
Narsieh. The
New Book of Tang reconciles by stating that Peroz died during his first visit to
Luoyang after receiving the title
Youwuwei Jiangjun and it was Peroz's son,
Narsieh, a hostage at the Tang court, was escorted by Pei Xingjian westwards to Persia in 679 (not 678) then spent 20 years in Tokhara. Finally, it was again Narsieh and not Peroz who received the title of
Zuoweiwei Jiangjun. .
The Gathering of Kings (王会图), circa 650 CE Statues of him and
Nanmei (probably
Wahram), were erected at the
Mausoleum of Emperor Gaozong. ==Descendants==
