  The Silk Road was a Eurasian trade route that played a large role in global communication and interaction. It stimulated cultural exchange; encouraged the learning of new languages; resulted in the trade of many goods, such as silk, gold, and spices; and also spread religion and disease. It is even claimed by some historians – such as Andre Gunder Frank, William Hardy McNeill, Jerry H. Bentley, and Marshall Hodgson – that the Afro-Eurasian world was loosely united culturally, and that the Silk Road was fundamental to this unity. This major trade route began with the Han dynasty of China, connecting it to the Roman Empire and any regions in between or nearby. At this time, Central Asia exported horses, wool, and jade into China for the latter's silk; the Romans would trade for the Chinese commodity as well, offering wine in return. The Silk Road would often decline and rise again in trade from the Iron Age to the post-classical era. Following one such decline, it was reopened in Central Asia by Han dynasty general Ban Chao during the 1st century.
  
  There were vulnerabilities as well to changing political situations. The rise of Islam changed the Silk Road, because Muslim rulers generally closed the Silk Road to Christian Europe to an extent that Europe would be cut off from Asia for centuries. Specifically, the political developments that affected the Silk Road included the emergence of the Turks, the political movements of the Byzatine and Sasanian Empires, and the rise of the Arabs, among others.
  
  The Silk Road flourished again in the 13th century during the reign of the Mongol Empire, which through conquest had brought stability in Central Asia comparable to the Pax Romana. It was claimed by a Muslim historian that Central Asia was peaceful and safe to transverse.
  
  "(Central Asia) enjoyed such a peace that a man might have journeyed from the land of sunrise to the land of sunset with a golden platter upon his head without suffering the least violence from anyone."
  
  As such, trade and communication between Europe, East Asia, South Asia, and West Asia required little effort. Handicraft production, art, and scholarship prospered, and wealthy merchants enjoyed cosmopolitan cities. Notable Travelers including Ibn Battuta, Rabban Bar Sauma, and Marco Polo traveled across North Africa and Eurasia freely, those that left accounts of their experiences inspired future adventurers. The Silk Road was also a major factor in spreading religion across Afro-Eurasia. Muslim teachings from Arabia and Persia reached East Asia. Buddhism spread from India, to China, to Central Asia. One significant development in the spread of Buddhism was the carving of the Gandhara School in the cities of ancient Taxila and the Peshwar, allegedly in the mid 1st century. In addition to commercial travel was the esteem of pilgrimage that existed across all of Afro-Eurasia, in the words of world historian R. I. Moore "if any single institution 'made' the Eurasian Middle Ages it was pilgrimage."
  
  Nevertheless, after the 15th century, the Silk Road disappeared from regular use. This was primarily a result from the growing sea travel pioneered by Europeans, which allowed the trade of goods by sailing around the southern tip of Africa and into the Indian Ocean.
  
  The route was vulnerable to spreading plague. The Plague of Justinian originated in East Africa and had a major outbreak in Europe in 542 causing the deaths of a quarter of the Mediterranean's population. Trade between Europe, Africa, and Asia along the route was at least partially responsible for spreading the plague. Eight centuries later, the Silk Road trade played a role in spreading the infamous Black Death. The disease, spread by rats, was carried by merchant ships sailing across the Mediterranean that brought the plague back to Sicily, causing an epidemic in 1347.
