One major conflict was the Battle of Talas in 751 CE, between the Chinese Tang Dynasty and the Abbasid Caliphate. This battle is considered to be a turning point in the history of Central Asia, as it resulted in the defeat of the Chinese and the spread of Islam into the region.
Another conflict was the Mongol invasions of the 13th century, which saw the Mongol Empire conquer vast swathes of territory across Eurasia, including parts of the Silk Roads. These invasions resulted in widespread destruction and loss of life, and also led to the decline of the Silk Roads as a major trade route.
In addition to these major conflicts, there were also a number of smaller-scale conflicts that occurred along the Silk Roads, such as raids by bandits and clashes between different ethnic groups. These conflicts were often related to competition for resources, such as water and grazing land, as well as religious and political differences.
Overall, while the Silk Roads were primarily a network for trade and cultural exchange, they were also the scene of a number of conflicts that had a significant impact on the history of the region.
