Explanation:

The Yuan Dynasty was a Chinese dynasty founded by the Mongol invaders.

The last years of the Yuan dynasty were marked by struggle, hunger and discontent among the population. Over time, the successors of Kublai Khan lost all influence in the other Mongolian lands in Asia, since the Mongols beyond the Middle Kingdom saw them as too Chinese. Gradually, they also lost influence in China. The reigns of the last Yuan emperors were short and were marked by intrigues and rivalries. Without interest in the administration, they were separated from both the army and the population, and China was torn apart by dissension and disquiet. The outlaws devastated the country without the interference of the Yuan armies.

From the end of the 1340s onwards, the inhabitants of the countryside suffered frequent natural disasters such as droughts, floods and resulting famines, the lack of effective government policies led to the loss of popular support. In 1351, the Red Turbans Revolt began and became a national uprising. In 1354, when Toghtogha led a large army to crush the rebels, Toghun Temür fired him suddenly for fear of treason. This resulted in the restoration of Toghun Temür's power on the one hand and the rapid weakening of the central government on the other. Having no choice but to rely on the military power of the local warlords, he gradually lost interest in politics and ceased to intervene in political struggles. He fled north to Shangdu (present-day Beijing) in 1368 after the approach of the forces of the Ming Dynasty (1368-1644), founded by Zhu Yuanzhang in the south. He tried to recover Khanbaliq, but ultimately he failed; died in Yingchang (located in present-day Inner Mongolia) two years later (1370). Yingchang was captured by the Ming shortly after his death. Some descendants of the royal family still live in Henan today.

The Prince of Liang, Basalawarmi, established a separate pocket of resistance to the Ming in Yunnan and Guizhou, but his forces were decisively defeated by the Ming in 1381. By 1387, the remaining Yuan forces in Manchuria under Naghachu had also surrendered to the Ming dynasty. The remains of the Yuan were withdrawn to Mongolia after the fall of Yingchang in 1370, where the name of Great Yuan continued to be used formally, and is known as the Northern Yuan Dynasty.
