How did Ogodei and Khubiliai Khan successfully administer their empires?
The Mongols were able to successfully administer empires largely because they treated their subjects well. They tended to give the people they conquered a relatively large role in governing themselves. In addition to this, they tended to be culturally tolerant. They did not impose their religion on the people they conquered. Instead, they allowed and even supported other religions. As an example of this, Khubilai Khan became a Buddhist and set out policies that helped both Buddhism and Confucianism. Finally, the Mongols provided safety and a fair amount of prosperity to the people they ruled. By acting in such relatively benevolent ways (and by brutally punishing any area that rebelled) the Mongols were able to successfully administer their empire.
