Overview and identity

Dayuan (大宛, "Great Yuan") is the name Chinese sources give to a kingdom in the Ferghana Valley, the fertile basin of the upper Syr Darya now shared by Uzbekistan, Kyrgyzstan and Tajikistan. It is not the Yuan dynasty of 1271–1368, which has its own entry. The border data behind this map labels the Ferghana kingdom "Great Yuan", a literal rendering of the Chinese name. Dayuan is known almost entirely from Chinese histories, above all the Shiji of Sima Qian and the Book of Han, which describe it from the 130s BC as a settled, urban state of walled towns, vineyards and exceptionally fine horses.

Origins and background

Ferghana lay at the far north-eastern edge of the Persian and then the Hellenistic world. Alexander the Great campaigned there in 329 BC and founded Alexandria Eschate, "Alexandria the Furthest", near modern Khujand. The valley afterwards belonged to the Seleucid and then the Greco-Bactrian sphere, until nomadic migrations around 160–130 BC — the Saka pushed south by the Yuezhi, the Yuezhi in turn driven west by the Wusun — cut it off from Bactria. Who the people of Dayuan were is debated. One long-standing theory reads "Yuan" as a rendering of Yavana, the Indian word for Greeks, and sees Dayuan as the descendants of Greek settlers; others stress its Iranian and Saka population and a Saka ruling class. The Chinese record a king's name, Mu-Kua, which has been read as a Saka name, and describe the men as deep-eyed and heavily bearded.

Chronology and relations with Han China

The Han envoy Zhang Qian passed through Dayuan around 130 BC on his mission to the Yuezhi, and his report made the kingdom famous at the Han court: some 70 walled towns, a population the Chinese put at 300,000, grape wine stored for decades, and the "heavenly horses" the Han wanted for their cavalry against the Xiongnu. When Dayuan refused to trade its horses and Han envoys were killed, Emperor Wu sent General Li Guangli west in 104 BC. The first expedition failed; a much larger second army reached the capital, Ershi, around 102 BC and besieged it for some forty days. The nobles of Dayuan killed their king, delivered his head and offered the horses. Li Guangli installed a pro-Han king and returned about 100 BC with several thousand horses — the War of the Heavenly Horses, which carried Han power deep into the Western Regions. Dayuan stayed in the Han orbit as a tributary kingdom. In the middle of the 1st century AD, according to the Book of the Later Han, Xian, the powerful king of Suoju (Yarkand), attacked Dayuan when it stopped paying tribute, deposed its king Yan Liu and set up a ruler of his own, until attacks from neighbouring Kangju forced Yan Liu's return.

Government, economy and culture

Chinese accounts describe a kingdom with a king, a viceroy and a council of nobles strong enough to depose him, and a professional army of about 60,000. Its wealth rested on irrigated farming in the valley — grapes, alfalfa, grain — and on horse breeding. After Zhang Qian's embassy, grapes and alfalfa were brought to China and planted around the imperial palaces. The Shiji notes that the peoples from Dayuan westward spoke different but mutually intelligible languages, prized trade, and held women in high respect.

Decline and legacy

Dayuan never fell in a single event; it simply fades from the record under that name. Later Chinese sources know the valley under other names, and it remained a crossroads of Silk Road trade and a prize for successive steppe and Iranian powers. Its lasting significance is as the scene of one of the first large-scale encounters between China and the urban civilisations of Central Asia: the horse trade and the war it provoked helped open the overland routes that became the Silk Road, and the "heavenly horses" of Ferghana stayed a legend in Chinese art for a thousand years.
