The Tian-shan corridor is one section or corridor of this extensive overall Silk Roads network. Extending across a distance of around 5,000 km, it encompassed a complex network of trade routes extending to some 8,700 km that developed to link Chang’an in central China with the heartland of Central Asia between the 2nd century BC and 1st century AD, when long distance trade in high value goods, particularly silk, started to expand between the Chinese and Roman Empires. It flourished between the 6th and 14th century AD and remained in use as a major trade route until the 16th century.
The extremes of geography along the routes graphically illustrate the challenges of this long distance trade. Falling to 154 metres below sea level and rising to 7,400 metres above sea level, the routes touch great rivers, alpine lakes, crusty salt flats, vast deserts, snow-capped mountains and ‘fecund’ prairies. The climate varies from extreme drought to semi-humid; while vegetation covers temperate forests, temperate deserts, temperate steppes, alpine steppes and oases. Read more
