Our world was made on and by the Silk Roads. For millennia it was here that East and West encountered each other through trade and conquest, leading to the spread of ideas and cultures, the birth of the world's great religions, the appetites for foreign goods that drove economies and the growth of nations. From the first cities in Mesopotamia to the growth of Greece and Rome to the depredations by the Mongols and the Black Death to the Great Game and the fall of Communism, the fate of the West has always been inextricably linked to the East. The Silk Roads vividly captures the importance of the networks that crisscrossed the spine of Asia and linked the Atlantic with the Pacific, the Mediterranean with India, America with the Persian Gulf.
