Final answer:
Kublai Khan relocated his capital from Karakorum in Mongolia to Beijing in northern China in 1264, which signified the Mongols' integration of Chinese governance systems and the start of the Yuan dynasty.
Step-by-step explanation:
The historical figure in question is Kublai Khan, who moved his capital from Karakorum in Mongolia to a city in northern China known as Beijing. This move took place in 1264, and Beijing was strategically chosen because it was near the old Jin capital of Zhongdu, which is also part of modern Beijing. Kublai Khan's establishment of his capital in Beijing marked a significant shift in power, signifying the Mongols' integration of Chinese systems of governance and the establishment of the Yuan dynasty.
By choosing Beijing as his capital, Kublai Khan not only strategically positioned himself near historical centers of influence but also underscored the synthesis of Mongol and Chinese elements in his rule, shaping the trajectory of the Yuan dynasty in the 13th century.
