Ban Chao (Chinese: 班超; pinyin: Bān Chāo; Wade–Giles: Pan1 Ch'ao1; 32–102 CE), courtesy name Zhongsheng, was a Chinese military general, explorer and diplomat of the Eastern Han Dynasty. He was born in Fufeng, now Xianyang, Shaanxi. Three of his family members — father Ban Biao, elder brother Ban Gu, younger sister Ban Zhao — were well known historians who wrote the historical text Book of Han, which recorded the history of the Western Han Dynasty. As a Han general and cavalry commander, Ban Chao was in charge of administrating the "Western Regions" (Central Asia) while he was in service. He also led Han forces for over 30 years in the war against the Xiongnu and secured Han control over the Tarim Basin region. He was awarded the title "Protector General of the Western Regions" by the Han government for his efforts in protecting and governing the regions.
Despite Ban Biao's status as a well-known historian, Ban Chao's family was poor and he worked as a copy-clerk for the government. Emperor Ming himself thought highly of him, and appointed him to be a clerk in the orchid terrace, but Ban Chao was too ambitious to be satisfied with a position like that, and was dismissed later. He was said to be a strong willed young adult with complete disregard for formal conduct. After his brother Ban Gu was removed from his post for his works on the Former Han, Ban Chao argued his case. When his brother was appointed to the imperial library, Ban Chao and his mother moved to the imperial capital Luoyang to accompany him. In 73 however, General Dou Gu embarked on an expedition to attack the Xiongnu, and Ban Chao was appointed as an assistant major. He distinguished himself in command against a Xiongnu detachment, and was appointed by Dou Gu to accompany Officer Guo Xun on a preliminary embassy to the remote western regions. When the group arrived at the capital of Shanshan, King Guang also received an embassy from the Northern Xiongnu. Ban Chao and the small group of delegates slaughtered the Xiongnu envoys and sent their heads to the king. Shocked and overwhelmed by Han brutality, King Guang sent hostages to Han as a pact of non-aggression. This was just the start of the many exploits Ban Chao accomplished in the western regions.
Ban Chao, like his predecessors Huo Qubing and Wei Qing from the Former Han Dynasty before him, was effective at expelling the Xiongnu from the Tarim Basin, and brought the various people of the Western Regions under Chinese rule during the second half of the 1st century CE, helping to open and secure the trade routes to the west. He was generally outnumbered, but skillfully played on the divisions among his opponents. The kingdoms of Khotan and Kashgar came under Chinese rule by A.D. 74. "Pan Ch'ao crushed fresh rebellions in Kashgar (80,87) and Yarkand (88), and made the Wusun of the Ili his allies."
Ban Chao was recalled to Luoyang, but then sent again to the Western Region area four years later, during the reign of the new emperor Han Zhang Di. He obtained the military help of the Kushan Empire in 84 in repelling the Kangju who were trying to support the rebellion of the king of Kashgar, and the next year in his attack on Turpan, in the eastern Tarim Basin. Ban Chao ultimately brought the whole of the Tarim Basin under Chinese control.
In recognition for their support to the Chinese, the Kushans (referred to as Da Yuezhi in Chinese sources) requested, but were denied, a Han princess, even though they had sent presents to the Chinese court. In retaliation, they marched on Ban Chao in 90 CE with a force of 70,000 but were defeated by the smaller Chinese force. The Yuezhi retreated and paid tribute to the Chinese Empire. (Later, during the Yuanchu period, 114-120 CE, the Kushans sent a military force to install Chenpan, who had been a hostage among them, as king of Kashgar).
In 91 CE, Ban Chao finally succeeded in pacifying the Western Regions and was awarded the title of Protector General and stationed at Qiuci (Kucha). A Wuji Colonel was re-established and, commanding five hundred soldiers, stationed in the Kingdom of Nearer Jushi, within the walls of Gaochang, 29 kilometres southeast of Turfan. In 94 CE, Chao proceeded to again attack and defeat Yanqi [Karashahr]. Subsequently, more than fifty kingdoms presented hostages, as submission to the Han Dynasty.
In 97 CE Ban Chao sent an envoy, Gan Ying, who reached the Persian Gulf or the Black Sea and left the first recorded Chinese account of Europe. Some modern authors have claimed that Ban Chao advanced to the Caspian Sea, however, this interpretation has been criticized as a misreading.
In 102 CE Ban Chao was retired as Protector General of the Western Regions due to age and ill health, and returned to the capital Luoyang at the age of 70, but the following month died there in the 9th month of the 14th Yongyuan year (30th Sept. to 28th Oct., 102). See: Hou Hanshu, chap 77 (sometimes given as chap. 107). Following his death, the power of the Xiongnu in the Western Territories increased again, and subsequent Chinese emperors were never able to reach so far to the west.
Ban Chao also belonged to a family of historians. His father was Ban Biao (3-54 CE) who started the History of the Western Han Dynasty (Hanshu; The Book of Han) in 36, which was completed by his son Ban Gu (32-92) and his daughter Ban Zhao (Ban Chao's brother and sister). Ban Chao was probably the key source for the cultural and socio-economic data on the Western Regions contained in the Hanshu.
Ban Chao's youngest son Ban Yong (班勇 Bān Yŏng) participated in military campaigns with his father and continued to have a central military role in the Tarim Basin into the 120s.
