What was one of the main factors that allowed long-distance trade during the time of the Islamic caliphates and Chinese dynasties?

One of the main factors that facilitated long-distance trade during the time of the Islamic caliphates and Chinese dynasties was the strong political stability in trade regions. Political stability helped to create environments where trade could flourish due to more secure trade routes, established governance that protected merchants, and reduced the risks associated with traveling and engaging in commerce.

Under the Islamic caliphates, a vast network of trade routes extended across the Middle East and beyond. This was aided by the political unity and administration brought about by Islamic governance, which encouraged the exchange of goods and ideas. Similarly, in China, dynasties like the Tang and Song established strong centralized states that contributed to the security and effectiveness of the Silk Road and other trade networks. The stability allowed for easier communication and consistency in trade policies, fostering increased economic activities across regions.

Cultural exchanges and trade were often mutually reinforcing; however, a decline in cultural exchanges would not support the growth of trade but rather diminish it. Increased risk management and advancements in maritime navigation were also significant, but without the foundational aspect of political stability ensuring safe conditions, those factors would be less effective.
