Genghis Khan had an empire.
 Genghis Khan also codified the Mongol legal system, promoted religious tolerance, and encouraged pan-Eurasian trade through the Pax Mongolica
 Genghis Khan also recognized the need for administrators to govern cities and states conquered by him, and so invited a Khitan prince, Chu'Tsai, who had experience governing cities and worked for the Jin dynasty before being captured by the Mongol army
