Zoroastrianism developed before 1,000 BCE and was the state religion in the Persian Empire for over thousand years until the conversion to Islam.
Therefore, it dominated the Western part of the historic Silk Road including Sogdania. Sogdian merchants in particular spread this religion all the way to China as they established trading colonies in the larger oasis cities along the route.
With the Muslim conquest of Persia in the 7th century, a centuries long religious transformation along the Silk road started that led to the domination of Islam in Central Asia as we know it today.
Samarkand and Bukhara in historic Sogdania are well known for their Islamic World Heritage and the Uyghurs of the Tarim Basin are Sunni Muslims.
Inventions that changed the World
Apart from religion, technology spread along the trails of the Silk Road. The Chinese secrets of silk, paper and gunpowder are three examples that changed World history:
- While Chinese silk was traded westwards, the secret of making this textile slowly made its way out of China as well. Cities in the Tarim Basin had they own silk industry in the 1st century CE, northern India around the 3rd century and the Byzantium Empire by the 5th century
- Paper making was another Chinese invention that spread West. The Muslim World came across paper during the conquest of Chinese controlled Sogdania in the 8th century. The first Muslim paper mill operated in Samarkand and paper soon was known throughout the Islamic World. Paper was essential for the spread of knowledge. The Islamic World was well advanced compared to Europe during that period and the availability of paper played a part in that.
- Gunpowder, as a final example, was invented in China in the 9th century CE. When the historic Silk Road opened during the Mongol conquests in the 13th century, firearms appeared almost at the same time in India, the Middle East and Europe. European countries then improved firearms and used them to dominate the World in the following centuries.
Conclusion
The network of the historic Silk Road helps to understand the geography and history of Central Asia, an area that is somewhat neglected in the traditional Western view.
This is completely unjustified as Central Asia is fascinating from a historical, cultural and geographical perspective.
I can recommend the books below for further exploration of this topic.
– Peter Frankopan, The Silk Roads, A New History of the World, Bloomsbury, 2015
This is a book about World history. But expect to see topics you think you know (Imperialism, Cold War, etc) from a different perspective – that of Central Asia. Highly recommended.
– Valerie Hansen, The Silk Road – A New History, Oxford University Press, 2012
Valeria Hansen looks in detail at a number of archeological sites in Central Asia and explains how the artifacts found there tell us about the historic Silk Road. A fascinating book.
– James A. Millward, The Silk Road – A Very Short Introduction, Oxford University Press, 2013
150 pages in pocket book format. A highly condensed and informative read.
