History of silk
The production of silk originated in Neolithic China within the Yangshao culture. Though it would later reach other places in the world, the art of silk production remained confined to China until the Silk Road opened at 114 BC. Even after trade opened, China maintained a virtual monopoly over silk production for another thousand years. The use of silk within China was not confined to clothing alone, and silk was used for a number of applications, such as writing. Within clothing, the color of silk worn also held social importance, and formed an important guide of social class during the Tang dynasty of China.
Silk cultivation had reached Japan by 300 AD, and by 552 AD the Byzantine Empire managed to obtain silkworm eggs and were able to begin silkworm cultivation while the Arabs also started to manufacture silk at around the same time. As a result of the spread of sericulture, Chinese silk exports became less important, although they still maintained dominance over the luxury silk market. The Crusades brought silk production to Western Europe, in particular to many Italian states, which saw an economic boom exporting silk to the rest of Europe. Developments in the manufacturing technique also started to take place during the Middle Ages in Europe, with devices such as the spinning wheel first appearing at this time. During the 16th century, France joined Italy in developing a successful silk trade, although the efforts of most other nations to develop a silk industry of their own were unsuccessful.
The Industrial Revolution changed much of Europe's silk industry. Due to innovations in the spinning of cotton, cotton became much cheaper to manufacture, leading to cotton production becoming the main focus for many manufacturers, and causing the more costly production of silk to shrink. New weaving technologies, however, increased the efficiency of producing silk cloth; among these was the Jacquard loom, developed for the production of highly detailed silks with embroidery-like designs. An epidemic of several silkworm diseases at this time caused production to fall, especially in France, where the industry never fully recovered.
In the 20th century, Japan and China regained their earlier dominant role in silk production, and China is now once again the world's largest producer of silk. The rise of new imitation silk fabrics, such as nylon and polyester, has reduced the prevalence of silk throughout the world, being cheaper and easier to care for. Silk is now once again thought of as a luxury good, with a greatly reduced importance compared to its historical heyday.
Early history
First appearance of silk
The earliest evidence of silk dates back to more than 8,500 years ago and has been found at the early Neolithic Age tombs of Jiahu, China. Biomolecular evidence, reported from a study, showed the existence of prehistoric silk fibroin in the tombs. Rough weaving tools and bone needles were also excavated, indicating the possibility that the Jiahu residents may also have possessed basic weaving and sewing skills required for making textiles. Other evidence of silk include items found at sites of the Yangshao culture in Xia County, Shanxi, where a silk cocoon was found cut in half by a sharp knife, dating back to between 4000 and 3000 BC. The species was identified as Bombyx mori, the domesticated silkworm. Fragments of a primitive loom can also be seen from the sites of Hemudu culture in Yuyao, Zhejiang, dated to about 4000 BC.The earliest extant example of a woven silk fabric is from 3630 BC, used as wrapping for the body of a child. The fabric comes from a Yangshao site in Qingtaicun at Rongyang, Henan. Similar remains of silk fabric were discovered at another Yangshao site located in Wanggou, Henan, in the year 2019. The fabric was used to wrap the body of a child placed inside a burial urn. Scraps of silk were found in a Liangzhu culture site at Qianshanyang in Huzhou, Zhejiang, dating back to 2700 BCE. Other fragments have been recovered from royal tombs in the Shang dynasty.
During the later epoch, the knowledge of silk production was spread outside of China, with the Koreans, the Japanese and, later, the Indian people gaining knowledge of sericulture and silk fabric production. Allusions to the fabric in the Old Testament show that it was known in Western Asia in biblical times. Scholars believe that starting in the 2nd century BC, the Chinese established a commercial network aimed at exporting silk to the West. Silk was used, for example, by the Persian court and its king, Darius III, when Alexander the Great conquered the empire.
Even though silk spread rapidly across Eurasia, with the possible exception of Japan, its production remained exclusively Chinese for three millennia. The earliest examples of silk production outside China are from silk threads discovered from the Chanhudaro site in the Indus Valley civilisation, which are dated to 2450–2000 BC. The analysis of the silk fibres shows presence of reeling and sericulture, and predates another example of silk found in Nevasa in peninsular India, dated to 1500 BC.
The Siberian Ice Maiden, discovered in the Pazyryk burials, was found clad in a long crimson-and-white striped woolen skirt, with white felt stockings. Her yellow blouse was originally thought to be made of wild tussah silk, but closer examination of the fibres revealed the material not to be Chinese in origin, and was instead woven from a wild silk of a different origin, potentially India.
Myths and legends
Many myths and legends exist about origin of silk production. The writings of both Confucius and other Chinese traditions tell a story about Empress Leizu; one day, in about 3000 BC, a silk worm's cocoon fell into her teacup. Wishing to extract it from her drink, the 14-year-old girl began to unroll the thread of the cocoon. Seeing the long fibers that constituted the cocoon, the Empress gathered other cocoons and wove it into cloth. Having observed the life of the silkworm on the recommendation of her husband, the Yellow Emperor, she began to instruct her entourage in the art of raising silkworms - sericulture. From this point, the girl became the goddess of silk in Chinese mythology.Knowledge of silk production eventually left China via the heir of a princess who was promised to a prince of Khotan, likely around the early 1st century AD. The princess, refusing to go without the fabric that she loved, decided to break the imperial ban on silkworm exportation.
Though silk was exported to foreign countries in great amounts, sericulture remained a secret that the Chinese carefully guarded; consequently, other cultures developed their own accounts and legends as to the source of the fabric. In classical antiquity, most Romans, great admirers of the cloth, were convinced that the Chinese took the fabric from tree leaves. This belief was affirmed by Seneca the Elder in his work Phaedra, and by Virgil in his work Georgics. Pliny the Elder notably accurately determined where silk came from; speaking of the Bombyx or silk moth, he wrote in his Natural History that, "They weave webs, like spiders, that become a luxurious clothing material for women, called silk."
Silk usage in Ancient and Medieval China
In China, silkworm farming was originally restricted to women, and many women were employed in the silk-making industry. Even though some saw the development of a luxury product as useless, silk provoked such a craze among the high society that the rules in the were used to limit its use to the members of the imperial family.For approximately a millennium, the right to wear silk was reserved for the emperor and the highest dignitaries. Silk was, at the time, a sign of great wealth, due to its shimmering appearance, created by the silk fiber's prismatic structure, which refracted light from every angle. After some time, silk gradually extended to other classes of Chinese society, though this was mainly the uppermost noble classes. Silk began to be used for decorative means and also in less luxurious ways; musical instruments, fishing, and bow-making all utilized silk. Peasants, however, did not have the right to wear silk until the Qing dynasty.
Paper was one of the greatest discoveries of ancient China. Beginning in the 3rd century BC, paper was made in all sizes with various materials. Silk was no exception, and silk workers had been making paper since the 2nd century BC. Silk, bamboo, linen, wheat and rice straw were all used, and paper made with silk became the first type of luxury paper. Researchers have found an early example of writing done on silk paper in the tomb of a marchioness, who died around 168, in Mawangdui, Changsha, Hunan. The material was more expensive, but also more practical than bamboo slips. Treatises on many subjects, including meteorology, medicine, astrology, divinity, and even maps written on silk have been discovered.

During the Han dynasty, silk became progressively more valuable in its own right, and was used in a greater capacity than as simply a material; lengths of silk cloth were used to pay government officials and to compensate citizens who were particularly worthy. In the same manner that one would sometimes estimate the price of products according to a certain weight of gold, a length of silk cloth became a monetary standard in China, in addition to bronze coins. Many neighbouring countries began to grow envious of the wealth that sericulture provided China, and beginning in the 2nd century BC, the Xiongnu people regularly pillaged the provinces of the Han Chinese for around 250 years. Silk was a common offering by the emperor to these tribes in exchange for peace.
Silk is described in a chapter of the from the Western Han period, and a surviving calendar for silk production in an Eastern Han document. The two other known works on silk from the Han period are lost.
For more than a millennium, silk remained the principal diplomatic gift of the emperor of China to neighbouring countries or vassal states. The use of silk became so important that the character for silk soon constituted one of the principal radicals of Chinese script.
As a material for clothing and accessories, the use of silk was regulated by a very precise code in China. For example, the Tang dynasty and Song dynasty used colour symbolism to denote the various ranks of bureaucrats, according to their function in society, with certain colours of silk restricted to the upper classes only. Under the Ming dynasty, silk began to be used in a series of accessories: handkerchiefs, wallets, belts, or even as an embroidered piece of fabric displaying dozens of animals, real or mythical. These fashion accessories remained associated with a particular position: there was specific headgear for warriors, for judges, for nobles, and others for religious use. The women of high Chinese society also followed these codified practices, and used silk in their garments alongside the addition of countless decorative motifs. A 17th-century work,, gives a description of one such motif:
