After Genghis Khan's death in 1227, his grandson, Kublai Khan, became the famous leader of the Mongol Empire. He reigned from 1260 to 1294 and is best known for founding the Yuan Dynasty in China, thus becoming the first non-Han emperor to rule the entire country. Kublai Khan expanded the empire's territories, implemented administrative reforms, and embraced cultural exchanges between the Mongol and Chinese civilizations. His rule marked a significant era of stability and prosperity, as he encouraged trade and tourism, famously inviting travelers like Marco Polo to embark on journeys across the vast empire.
