Answer :
According to mythology, sericulture and silk had moved overland from China to India around 140 BCE. By the second century CE, India was supplying Persia with its own raw silk and silk textiles. (A few centuries later, Japan acquired and established a robust sericulture.)
The Crusades introduced silk manufacturing to Western Europe, particularly to numerous Italian kingdoms, which experienced a boom in silk exports to the rest of Europe. During the Middle Ages, changes in manufacturing processes began to emerge, with equipment like as the spinning wheel making their debut.
