Silk Road [SEP] Introduction
The Chinese took great interest in the security of their trade products, and extended the Great Wall of China to ensure the protection of the trade route. The Silk Road trade played a significant role in the development of the civilizations of China, Korea, Japan, the Indian subcontinent, Iran, Europe, the Horn of Africa and Arabia, opening long-distance political and economic relations between the civilizations. Though silk was the major trade item exported from China, many other goods and ideas were exchanged, including religions (especially Buddhism), syncretic philosophies, sciences, and technologies like paper and gunpowder. So in addition to economic trade, the Silk Road was a route for cultural trade among the civilizations along its network.
