Answer: The right answer is the powerful Emperor Kublai Khan (1215-1294).
Explanation: Just to elaborate a little on the answer, it can also be added that serving at the court of Emperor Kublai Khan granted the Italian merchant Marco Polo (1254-1324) the opportunity to write some of the earliest accounts on China known at that time by the Europeans. Marco Polo and his relatives spent several years in China, and Kublai Khan thought very highly of them. They made a small fortune at the service of this ruler, but eventually returned to Venice.
