Explain an example of how trade helped to lead the spread of ideas and/or technology

Trade spreads ideas and culture because it involves people moving from place to place around the world as they trade.  As they move, they (and the people they meet) come into contact with new ideas and cultural practices.

Explanation:

For example, goods would be brought across the Middle East by camel caravans.  This meant that relatively large numbers of people would travel along with the goods.  They went slowly, stopping often.  When they stopped, they would interact with local people.  There would be exchanges of ideas.  People would see things like how other cultures cooked, what clothes they wore, and what religious ideas they believed in.  In those times, trade was a much more personal business that involved many people travelling.  As they traveled, they exposed the people they met to their own culture.  At the same time, they were exposed to the cultures of the places through which they traveled.  In these ways, trade spread ideas and culture, making it an important force in world history.

the mongolian invasion of china and central asia resulted in a disruption of the silk road as the chinese garrisons lost support from the chinese kingdoms which fell under the mongols. however, as the mongols established a formal dynasty in china, the successors of genghis khan restored the garrisons along the silk road allowing the safe travel caravans again.
