Trade Routes as Highways for Ideas
Key Idea
Trade routes like the Silk Road and sea lanes of the Indian Ocean were like highways for ideas. When traders and travelers met, they didn't just exchange silk and spices. They also shared their religions, stories, and technologies.
This movement of beliefs and practices from one culture to another is known as cultural diffusion. This process transformed societies across Asia, as religions like Buddhism and Islam found new followers in distant lands.
