I mentioned sometime back that a feature of civilization is that people like to buy and sell stuff. This is called commerce, where you trade something you have for something you want. The people of Western Europe traded with people of other civilizations—even as far away as China.
Trade goods were carried by merchants from Europe to China and back. They traveled along the Silk Road (actually several roads or routes) that crossed the whole continent of Asia. They’d take goods from Europe like horses, grapes, honey, gold & silver and trade them for Chinese goods like silk, tea, spices, rice, paper and gunpowder.
The Silk Road was originally set up by China’s Han Dynasty in 130 bc. Merchants didn’t necessarily travel its entire length—there were trading posts along the way. One section of the Silk Road was the Persian Royal Road. It was used as early as 500 bc to send messages across the MidEast. Messengers would stop at changing posts to hop on a fresh horse.
