It is noteworthy that in the Middle Ages the Great Silk Road was more active and crowded than in ancient times. This was due to the patronage of the trade development of large empires established in China, Central Asia and the Middle East, such as the Tang Empire (618-907 AD), the Arab Caliphate (632-1258 AD), and the Samani State (865-999 AD). The trade of the Silk Road, which has been active for many centuries, decreased for a while as a result of the Mongol invasion, which had a negative impact on the development of China and Central Asian countries by the 13th century, and it can be seen that only its northern branch developed.
