I want to know the answer to the following question:
When did the yuan dynasty start and end?
All the background I'm provided with is that "In his Kublai Khan: His Life and Times, Rossabi explains that Kublai "created government institutions that either resembled or were the same as the traditional Chinese ones", and he "wished to signal to the Chinese that he intended to adopt the trappings and style of a Chinese ruler".". Is that enough to answer the question?
