2.1 The Silk Roads

What made the Silk Roads work

The Silk Roads were an interconnected network of land trade routes linking China, Central Asia, the Middle East, India, and the Mediterranean. Key innovations enabled their growth: the caravanserai (roadside inns for rest and trade), camel domestication for desert travel, and the paper money and credit systems (like the flying cash) that reduced the need to carry heavy coinage.

Political power fueled trade

Strong states protected and profited from trade. The Chinese dynasties (Han, Tang, Song) guarded routes and taxed goods, while the Mongol Empire later unified much of Eurasia under the Pax Mongolica, making travel safer and boosting exchange. Goods traded included silk, porcelain, spices, precious metals, and horses.

More than just goods

The Silk Roads spread religions and ideas, not just products. Buddhism spread from India into Central Asia and China via merchants and monks; Islam later expanded along these same routes. Technologies like papermaking and artistic styles also diffused, showing how trade networks reshaped culture across Afro-Eurasia.
