Which Mongolian ruler is specifically noted for ruling over China?

The Mongolian ruler specifically noted for ruling over China is Kublai Khan. He was the grandson of Genghis Khan and played a crucial role in the establishment of the Yuan Dynasty in China, which marks an important period in Chinese history as it represented the first time that the entire country was united under foreign rule. Kublai Khan's reign began in 1260 and lasted until his death in 1294, and during this time, he implemented significant administrative reforms and promoted trade and cultural exchange along the Silk Road. His governance is characterized by efforts to integrate Mongol and Chinese traditions, leading to a unique blend of cultures that influenced Chinese history profoundly.

Genghis Khan, while a monumental figure and the founder of the Mongol Empire, primarily focused on the expansion of the empire across Asia and Europe rather than direct governance over China. Tamerlane, known as Timur, was a Central Asian conqueror from a later period, and Ögedei Khan, Genghis Khan's immediate successor, ruled over parts of the Mongol Empire but did not have the same direct rule over China that Kublai Khan exercised.
