What rebel leander became emperor after the mongols were driven out china? ?

After the Mongols were driven out of China, during the 14th century, due to the destruction that the corrupt Yuang dinasty had brought on the nation, a rebel leader by the name of Zhu Yuangzhang, later known as the Hongwu emperor, took control of the rebel forces and armies and was able to restore some order and peace. He became the founder and first emperor of the Ming dynasty.

Yuangzhang did not only become the first Ming emperor, but he was also responsible for the chinese forces being able to push the mongolians out of their territory and after claiming the Mandate of Heaven, he established the new ruling dynasty in the year of 1386. Also, during this year, him and his army invaded the city of Khanbaliq, the center of the Yuan dynasty, and turned it into his own headquarters. Khanbaliq later became known as Beijing. He ruled for a long time and made his many sons princes. However, his rule was ended when his own nephew attempted to dethrone him and the Ming Yongle Emperor took over.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
