Silk Road

Long ago, camel caravans trekked thousands of miles across the snowy mountains and scorching deserts of Asia. Along the way, people traded precious goods from distant empires. These trading routes are known today as the Silk Road. Travelers exchanged more than goods--they shared ideas, religions, and knowledge about subjects from astronomy to mathematics. The Road also helped spread art, music, and foods.
