Final answer:
The Mongols demanded heavy taxes, tribute, soldiers, obedience, and loyalty from their Russian subjects as part of their imperial control. This represents a characteristic of rising empires.
Step-by-step explanation:
The Mongols made several demands on their Russian subjects. They imposed heavy taxes and tribute on the Russian cities and required them to provide soldiers for the Mongol army. In addition, the Mongols demanded obedience and loyalty from the Russian princes and rulers, who were expected to acknowledge the supreme authority of the Mongol Khan.
This element of demanding tribute, soldiers, obedience, and loyalty from the subjects can be seen as a form of imperial control. It represents the Mongol Empire exerting its power and authority over the conquered territories, which is a characteristic of rising empires.
