Industrial Espionage

The Chinese produced luxury silk fabrics for several thousand years before they began trading with the west. Scraps of dyed silk gauze found in a neolithic site in Zhejiang Province date from 3600 BCE. Silk fabrics woven in complex patterns were produced in the same region by 2600 BCE. By the time of the Zhou dynasty, which controlled China from the twelfth to the third centuries BCE, silk was an established industry in China.

Wild silk, spun from the short broken fibers found in the cocoons of already-emerged silk moths, was produced throughout Asia. Only the Chinese knew how to domesticate the silk moth, bombyx mori, and turn its long fibers into into thread. They kept close control over the secrets of how to raise the domestic silkworm and create silk from the long fibers in its cocoon. Exporting silkworms, silkworm eggs or mulberry seeds was punishable by death. It was more profitable to export the finished product than the means of production.

The Chinese monopoly on the secrets of silk production and manufacture was eventually broken. According to one story, a Chinese princess, sent to marry a Central Asian king, smuggled out what silk cultivators called the “little treasures” as an unofficial dowry. (In one cringe-inducing version of this story, the princess carried the silkworms in her chignon to escape detection at the border.* It was illegal for a commoner, like a border security agent, to touch the head of a member of the royal family.) A totally different tradition tells of two Nestorian monks who smuggled silkworm eggs out of China in hollow staffs and carried them all the way to Byzantium, traveling in winter so the eggs wouldn’t hatch.

However the “little treasures” traveled, the Chinese monopoly on silk production was over by the sixth century CE, when the Middle Eastern cities of Damascus, Beirut, Aleppo, Tyre, and Sidon became famous for their silks.
