The Silk Road is the world's longest and most historically important overland trade route. Trade began thousands of years ago, and silk was one of the main trade items.
Through trade and travel along the road, the cultures throughout Eurasia developed economically, technologically and culturally, and religions and ideas spread east and west. The Han, Tang, and Yuan Empires especially prospered due to the trade, but during other eras, trade stopped for various reasons.
Not Actually a Single Road.... The Silk Road is actually the collective name given to a number of ancient overland trade routes that linked China, Central Asia, the Middle East, and Europe. The Silk Road trade with China passed through Xinjiang.
The long and winding routes in northern China followed the Gansu Corridor, a huge valley that is 1,000 kilometers long across Gansu Province. The valley's eastern end opened at Lanzhou, and the valley's western end opened near Dunhuang.
The routes started at the old capital cities of Luoyang and Xi'an, crossed the Yellow River at Lanzhou, and then followed the Gansu Corridor into Xinjiang. At Dunhuang, the route split three ways: the northernmost branch crossed north around the Tianshan Mountains and the other two crossed north and south of the Tarim Basin.
Silk, the most luxurious fabric of all, was almost exclusively made in China until the secret was revealed in the 7th century to the West. This precious commodity attracted Central Asian merchants who exchanged gold, horses, glassware, furs, ivory and jade.
New fruits and nuts were also introduced to the eastern civilizations by the traders: cucumbers, walnuts, sesame seeds, figs, alfalfa, and pomegranates.
Wheat that first originated in the Fertile Crescent was planted in the Gansu Corridor about 2,800 BC.
Varieties of millet, rice and other crops travelled the opposite way through the Gansu Corridor and reached western Asia and Europe from the fifth millennium to the second millennium BC.
Porcelain was another invention that was prized in the West. It was during the Han Dynasty era that the first kinds of brightly colored porcelain were manufactured and sent westwards, and especially during the Tang and Yuan eras, fine porcelain was a major export.
The prehistoric trade and travel across Eurasia is little known, but there is evidence of trade and travel to Xinjiang even 4,000 years ago. In the Shang Kingdom (1766-1122 BC), jade was highly valued, and they imported jade from an area of Xinjiang.
By the 1st millennium BC, people carried silk to Siberia through the Gansu Corridor over the northern branch of the Silk Road.
It is known that by around 600 BC, gold, jade, and silk was being traded between Europe and Western Asia and the advanced states of the Zhou Dynasty (1045–221 BC). Silk was found in a 6th century tomb in Germany.
Around 300 BC, civilizations active in the Silk Road trade included Ancient Greece, Persia, Sogdiana, Yuezhi, and the Qin State that controlled the eastern part of the Hexi Corridor (or Gansu Corridor in Gansu Province). This corridor is a huge very long valley that extends from Luoyang to Xinjiang.
To reach western Asia and Europe, products were transported through the Sogdian territories west of Xinjiang in modern day Uzbekistan and Tajikistan, and from the second century BC until the 10th century, the Sogdians dominated the Silk Road trade.
They were the Silk Road's most prominent merchants and middlemen for more than 1,000 years. They established a trading network across 1,500 miles from Sogdiana to the Chinese empires. The common lingua franca of the trade route was Sogdian. Many Sogdian documents were discovered in Turpan.
Originally, the people in the Han Empire (206 BC–220 AD) traded silk within the empire from the interior to the western borders.
The caravans were often attacked by small Central Asian tribes, and in order to protect their internal trade routes, the Han court sent General Zhang Qian (200–114 BC) as an envoy to build relationships with them.
Starting from Chang'an (today's Xi'an), the capital of the Western Han Dynasty (206 BC–9 AD), and crossing the vast Western Regions, Zhang reached the important small kingdoms of Loulan, Qiuzi, and Yutian and established trade relations with them.
Loulan, Qiuzi and Yutian were later all abandoned for unknown reasons, but travelers today can still see the ruins of these three once flourishing cities.
Zhang's officers went even further onwards into Central Asia. The countries Zhang and his delegation visited sent their envoys to Chang'an, and traders began to travel the trade routes to carry silk and ceramics to other parts of the world. The Han imported Roman glassware.
After the Han Empire fell in the year 220, from 220 to 581, the region was divided into three big warring states. At the same time during the 200s, barbarian attacks on the Roman Empire increased, and this further stymied trade with Europe.
During the 200s also, the Huns attacked states west of the Roman Empire, and this warfare decreased trading in Central Asia. About 400 AD, the Roman Empire collapsed. For these and other reasons, there was a decrease of trading through the Gansu Corridor to the West until the Tang Empire.
In the early Tang Dynasty (618–917) era, the Silk Road route in Xinjiang was controlled by Turkic tribes. They allied with small states in Xinjiang against the Tang.
The Tang Dynasty later conquered the Turkic tribes, reopened the route, and promoted trade. Trade with the West boomed.
The Sogdians played a major role in the Tang Dynasty trade and rose to special prominence in the military and government of the Tang dynasty (618–907 AD) court. Sogdian merchants and diplomats traveled as far west as the Byzantine Empire, and they established a trade network that stretched about 1,500 kilometers from Sogdiana to Tang territory.
The famous monk Xuanzang (602–664) traveled the Silk Road during this period. He began his trip from Chang'an (today's Xi'an), passed through the Hexi Corridor (the area west of the Yellow River), Hami (Xinjiang Region), and Turpan and continued westward to India.
At the time it was commonly believed that people in those states were brutal and wild, and Xuanzang was surprised by the warm reception he received along the way. His report contributed to the Tang government's improved relations with these tribes and kingdoms.
However, by 760 AD, the Tang Government lost control of the Western Region and trade on the Silk Road ceased.
The Tang Empire ended in 907, and there followed some decades of warfare until the Song Empire arose. The Song Empire was powerful, but they didn't have control of the Gansu Corridor.
The Western Xia was a kingdom in the northwest that controlled access to the strategic Gansu Corridor. The Song Dynasty thought that if they could regain the land of the Western Xia, they could perhaps reestablish the lucrative Silk Road trade that benefited the Han and Tang dynasties. They tried to conquer the country, but they couldn't.
Then, in 1127, the Song court was forced south of the Yangtze River, and the remaining Southern Song Empire was even further from the Silk Road route. Then in 1200s, the Mongols attacked them.
However, as the Mongol Empire expanded in Central Asia and Europe before the fall of the Southern Song Empire, they promoted and protected the trade on the western Silk Road routes.
Trade on the Silk Road revived and reached its zenith during the Yuan Dynasty (1271–1368), when China became dependent on its silk trade. Genghis Khan conquered all the small states, unified China, and built a large empire under his rule.
Marco Polo (1254–1324) traveled along the Silk Road visiting the Yuan capital city Dadu (today's Beijing). In his famous book about the Orient he mentions a special passport in the form of a board. It was issued by the Yuan government to the merchants to protect their trade and free movement within the country.
Other preferential treatment was also given to the merchants, and trade boomed. Silk was traded for medicines, perfumes, slaves, and precious stones.
As overland trade became increasingly dangerous, and travel by sea became easier and more popular, trade along the Silk Road declined.
The conquest of the Byzantium Empire and the Ottoman control of western Asia kept Europe and the empires of the Ming and Qing separated, and overland travel became dangerous. While trade of silk for furs with the Russians north of the original Silk Road continued, by the end of the fourteenth century, trade and travel along the route had decreased significantly.
In the 1400s, the Ming court policy shifted to isolationism. They stopped Silk Road trade. Also, there was less of a demand for silk and porcelain in the West. In the 1100s, Italians began producing their silk and textiles, and by the 1400s, Lyon was a major silk textile production center for the European market. In the 1700s, Europeans also produced porcelain and partly satisfied internal demand.
However, the Ming and Qing empires' trade in silk, but especially for the export of tea, continued with Tibet and southern Asia via the very old Tea Horse Road (Chama in Chinese) trade routes.
Yunnan and Sichuan were big exporters of tea for more than a thousand years to the Tibetan Empire. In return, the Tibetans exported horses and various products.
However, during modern times, maritime trade and the availability of Indian and Ceylon tea made the Tea Horse trade route obsolete.
Silk Road trade is reviving in part due to the improvement of land transport technology. The Chinese government has been talking about building highways and bullet train lines to connect China and Europe. These would follow the old routes and use the mountain passes such as the Gansu Corridor all the way to Athens.
However, not much practically has been built yet. There is a bullet train line between Lanzhou and Urumqi, but there isn't yet one west of Urumqi.
Partly due to the recent news of the Chinese government's interest in reviving Silk Road trade, there is increased interest in touring the ancient trade routes' main sites not only within China, but westwards. Some people are enjoying touring the old trade routes extending west from Greece into Central Asia.
Within China, there are many sites to explore. See Top Things to Do Along the Silk Road.
