The ancient Silk Road was a vast network of trade routes that linked East Asia, South Asia, the Middle East, Africa, and Europe. This map shows major cities such as Xi'an, Samarkand, Baghdad, and Rome, which served as centers of trade and cultural exchange. Spanning deserts, mountains, and seas, the Silk Road facilitated the exchange of goods such as silk, spices, textiles, and precious metals. It also promoted the spread of ideas, religions, and technologies. Sea routes across the Indian Ocean complemented land routes, linking ports such as Calcutta, Malacca, and Alexandria. The route shaped global history and intercontinental relations.
