Silk Road
A network of Eurasian trade routes linking China with Central Asia, India, Persia and the Mediterranean from roughly the 2nd century BCE.
Sogdian merchants: Central Asian traders from Samarkand and beyond who dominated Silk Road commerce as brokers and caravan operators for centuries. The middlemen who made relay trade across Central Asia work; their language became the route's lingua franca.
Zhang Qian: Han envoy sent west in 138 BCE who returned with reports of Central Asian states and markets for Chinese goods. His reconnaissance mission opened Han eyes to trade possibilities west of the mountains.
Marco Polo: Venetian merchant whose 13th-century account of Yuan China became Europe's best-known description of the East. The most famous account of travel along the route, accurate enough to be debated for centuries.
Dunhuang manuscripts: Tens of thousands of manuscripts sealed in the Mogao Caves' Library Cave until their 1900 discovery. A single hoard showing the languages, religions and record-keeping of one route city.
Spread of papermaking: Paper technology carried west after 751, reaching Samarkand, Baghdad and eventually Europe. The classic example of a technique transmitted along the route, transforming record-keeping in the Islamic world.
Dunhuang: Oasis town at the entry to the Hexi Corridor in Gansu, guarding the split of routes around the Taklamakan Desert. The chokepoint where westbound caravans provisioned before crossing or skirting the desert.
Emperor Wu of Han: Han emperor (r. 141–87 BCE) who expanded westward, establishing the Protectorate of the Western Regions to secure the corridors. His campaigns garrisoned the routes, turning diplomatic trails into a secured trade corridor.
Ibn Battuta: Moroccan traveler who covered roughly 120,000 km across the Muslim world in the 14th century, including Central Asian routes. Traveled the route's western stretches and recorded trade conditions under Mongol successor states.
Mogao Caves: A millennium of Buddhist cave temples at Dunhuang, decorated with murals fusing Indian, Chinese and Central Asian styles. The richest surviving artistic record of Buddhist transmission along the routes.
Black Death: The 14th-century plague pandemic that likely reached the Crimea via Eurasian trade networks before devastating Europe. The route moved disease as efficiently as commodities; the pandemic is its darkest consequence.
