East-West Communication During the Mongol Era

How did the Mongol conquests facilitate the spread of ideas, religions, inventions, and diseases?

The Mongol governments did more than any earlier political entities to encourage the movement of people and goods across Eurasia. With these vast movements came cultural accommodation as the Mongols, their conquered subjects, and their trading partners learned from one another. This cultural exchange involved both physical goods and the sharing of ideas, including the introduction of new religious beliefs and the adoption of new ways to organize and rule the Mongol Empire. It also facilitated the spread of the plague and the unwilling movement of enslaved captives.
