Silk production has a long and colourful history unknown to most people. Scientific discoveries have shown that silk production existed in China from around 2500 B.C., although it could be much older. For hundreds of years, China kept the secret of silk to itself as one for the most closely protected secrets in history. Anyone revealing the secret of silkworms or trying to take silkworm eggs out of ancient China was punished by death.

At one time silk was reserved only for the Chinese emperor. Gradually, others began wearing silk. In addition to being used for clothing, silk came to have industrial uses in ancient China, something that happened in the West only in modern times. Silk was used to make musical instruments, fishing lines, weapons, ropes and even paper. During the Han Dynasty silk became a form of money. Farmers paid taxes in both rice and silk. The prices of goods were calculated in lengths of silk just as they had once been calculated in gold. The importance of silk is even reflected in the Chinese language. For example, of the 5000 most common Chinese characters, around 500 have silk as their “key”.

In spite of their secrecy, the Chinese eventually lost their monopoly on silk production. It reached Korea in around 200 B.C. when immigrants from China arrived there. Silk production came to India in 300 A.D.. It was not until 500 A.D. that silk production came to Europe when travellers smuggled out silkworms in hollow tubes of bamboo. These were used to establish silk industry in Rome (modern-day Italy), although Chinese silk was still considered to be the best.

Silk was brought to Rome from China by means of the Silk Road. There were actually two Silk Roads, one over land and one on the sea. The land route in particular had a huge effect in history. All sorts of trade goods — silver, gold, jade, porcelain — passed along this road. Ideas travelled the Silk Road too. For example the religion of Buddhism was carried to China from India by traders on the Silk Road. The Silk Road created the first international culture, exposing many people to the ideas and treasures of both Western and Chinese cultures.
