WORLD HISTORY

Detailed explanation-1: -Kublai Khan was the grandson of Genghis Khan and the founder of the Yuan Dynasty in 13th-century China. He was the first Mongol to rule over China when he conquered the Song Dynasty of southern China in 1279.

Detailed explanation-2: -Major military efforts were taken by Kublai Khan of the Yuan dynasty in 1274 and 1281 to conquer the Japanese archipelago after the submission of the Korean kingdom of Goryeo to vassaldom.

Detailed explanation-3: -Kublai Khan wanted to unite all of China under his rule, including the Song in the south. In 1271, he renamed his empire the Yuan Dynasty to better appeal to his Chinese subjects, and he established his capital in modern-day Beijing. Eventually, most Song Chinese accepted Kublai’s rule.

Detailed explanation-4: -Most notably, the Mongol invasions of Japan in the 1270s and 1280s were disastrous for Kublai’s men. The Japanese decisively defeated the Mongol invaders, who lost tens of thousands of men in the failed ventures, and prevented the Mongol Empire from expanding into Japan.
