The "Great Capital" city of Daidu (which is now modern-day Beijing) was the capital city under the leadership of Kublai Khan.
The founder of the Mongol Empire is Genghis Khan. He united the Mongol tribes in the 12th and 13th centuries and successfully expanded the empire across Asia and Europe. Genghis Khan is known for his military tactics and his ability to establish a vast empire.
