The Silk Road is the most well-known trading route of ancient Chinese civilization. Trade in silk grew under the Han Dynasty ( 202 BC - AD 220) in the first and second centuries AD.
Originally, the Chinese trade silk internally, within the empire. Caravans from the empire's interior would carry silk to the western edges of the region. Often small Central Asian tribes would attack these caravans hoping to capture the traders' valuable commodities. As a result, the Han Dynasty extended its military defenses further into Central Asia from 135 to 90 BC in order to protect these caravans.
Chan Ch'ien, the first known Chinese traveler to make contact with the Central Asian tribes, later came up with the idea to expand the silk trade to include these lesser tribes and therefore forge alliances with these Central Asian nomads. Because of this idea, the Silk Road was born.
The route grew with the rise of the Roman Empire because the Chinese initially gave silk to the Roman-Asian governments as gifts.
