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.

1. Kublai Khan established the Yuan Dynasty and became its first emperor, unifying China and ruling over it for nearly 34 years.
2. He expanded the empire's territories, including the conquest of the Southern Song Dynasty, thus completing the Mongol conquest of China.
3. Kublai Khan promoted cultural exchange and innovation by inviting scholars, artists, and traders from different parts of the world to his court, contributing to the flourishing of Chinese arts, sciences, and commerce.
4. He developed infrastructure by constructing roads, canals, and improving transportation systems, facilitating trade and communication within the empire.
5. Kublai Khan promoted religious tolerance, allowing the practice of various religions in the empire and patronizing Buddhism, Daoism, and Confucianism.

The resulting stability brought by Mongol rule opened these ancient trade routes to a largely undisturbed exchange of goods between peoples from Europe to East Asia. Along the Silk Road, people traded goods such as horses, porcelain, jewels, silk, paper, and gun powder.
