I want to know the answer to the following question:
Who did Zhu Yuanzhang defeat?
All the background I'm provided with is that "The first emperor of the Ming dynasty, Zhu Yuanzhang (the Hongwu Emperor), who overthrew the Yuan dynasty, renamed the city Yingtian, rebuilt it, and made it the dynastic capital in 1368.". Is that enough to answer the question?
