What was the effect of the decline in trade after the fall of the roman empire

The Silk Road was a network of trade routes connecting China and the Far East with the Middle East and Europe. Established when the Han Dynasty in China officially opened trade with the West in 130 B. C., the Silk Road routes remained in use until 1453 A. D., when the Ottoman Empire boycotted trade with China and closed them. Although it's been nearly 600 years since the Silk Road has been used for international trade, the routes had a lasting impact on commerce, culture and history that resonates even today.
