Silk Road

The Silk Road was less one road than a relay of oasis routes crossing some 7,000 kilometres between Chang’an and the Mediterranean, stitched together by caravan cities such as Dunhuang, Turpan, Kashgar, and Samarkand. Official traffic began when Zhang Qian returned in 126 BCE from thirteen years of captivity and reconnaissance in Central Asia, handing the Han court both intelligence and grapevines; within a generation, silk bolts were priced in Rome and Buddhist monks walked the route eastward.

Dunhuang became the route’s memory bank: merchants funding cave chapels from 366 CE onward created the Mogao Grottoes’ 735 caves and 45,000 square metres of mural, sealed library cave included, inscribed by UNESCO in 1987. Ideas travelled with cargo — papermaking reached Samarkand after the Battle of Talas in 751, printing followed, and Nestorian, Manichaean, and Muslim communities left documents in a dozen languages in the Turfan sands. The modern revival is equally official: in 2014 UNESCO inscribed the 5,000-kilometre Chang’an–Tianshan corridor jointly with Kazakhstan and Kyrgyzstan, listing 33 sites along precisely these routes.
