How did Buddhism travel along the Silk Road?

Buddhism began in India around the 5th or 6th century BCE and spread along trade routes linking India, Central Asia and China. According to the International Dunhuang Programme, different strands of the religion travelled these routes between the 1st century BCE and the 7th century CE. Missionaries, monks, expanding empires, merchants, artisans and pilgrims all played a part. Asia Society describes Buddhism as the first great missionary faith to exploit the mobility the Silk Road offered. [1] [2]

Asia Society notes that Buddhism had spread into what are now Pakistan and Afghanistan by the 1st century BCE. Buddhist merchants from those areas built temples and shrines along the route, and the monks who staffed them preached to local people and passing travellers. The Met Museum adds that Buddhism in Gandhara and the Swat Valley was financed by the trade passing through the mountain passes, and that prosperous Buddhist complexes grew up at oases that served as way stations for traders crossing the deserts. [2] [3]

Monasteries emerged near irrigated oases such as Khotan, Kucha, Turfan and Dunhuang on the northern and southern branches of the routes. Stupas, cave paintings and manuscripts record this movement across Central Asia. [4]

Asia Society says the Chinese imperial court officially noted Buddhism's arrival in the mid-1st century CE, and that official and private support for temples and monasteries helped it grow. The International Dunhuang Programme says the spread toward China accelerated in the 2nd century CE, thanks to the Kushan Empire's expansion into Central Asia and its Buddhist missionaries. A Buddhist community existed in the capital Loyang by the second century. [2] [5] [4]

Early translators of Buddhist texts into Chinese included Parthian, Sogdian and Indian monks, and later figures such as Dharmaraksa and Kumarajiva, who came from Buddhist centres in the Tarim Basin. From the 4th century CE, Chinese monks such as Faxian and Xuanzang travelled to India in the opposite direction. From China, Buddhism reached Korea and Japan by the 6th century. [4] [1] [2]

The IIAS cautions that the term Silk Routes can mislead. Much trade was short-distance and regional, so few individuals travelled the whole way. It suggests thinking of a relay race, with the faith passed from one group to the next. Buddhism also spread west into Bactria, but the source says it is not known how far west it went or why it stopped. [6]

Language shaped the transmission. Texts were sometimes kept in Sanskrit and sometimes translated into local tongues, producing a multilingual literature in Khotanese, Sogdian, Uigur, Tibetan and Chinese, among others. The Chinese undertook what the IIAS calls the greatest translation project in world history. [6]

Disruption also moved people. The Met Museum reports that Hun invasions between 450 and 520 appear to have pushed Gandharan monks into Afghanistan and western Central Asia. [3]
