There were two main overland trade routes of the Silk Road: the northern and the southern routes. The northern route started in China and went through Central Asia, around the Caspian Sea to the Black Sea, and then on to Europe. The southern route started in China, went through India, and then on to Europe.
The Silk Road was used to trade a variety of goods, including silk, gold, silver, ivory, spices, and gems. The Silk Road was also used for cultural exchange, as people from different cultures traveled along the Silk Road and shared their ideas.
