Kublai-khan definition

His great successor, Kublai Khan (1280-1294), rebuilt the town, which he called Yenking, and which became known in Chinese as Ta-tu, or "great court," and in Mongolian as Khanbalik (Cambaluc), or "city of the khan."

Under the Kin dynasty the walls extended to the south-west of the Tatar portion of the present city, and the foundations of the northern ramparts of the Khan-balik of Kublai Khan are still to be traced at a distance of about 2 m.

In the south-eastern portion of the Tatar city used to stand the observatory, which was built by order of Kublai Khan in 1296.

China proper, minus these external provinces, was again united under the Sung dynasty (960-1127), but split into the northern (Tatar) and southern (Chinese) kingdoms. In the 13th century arose the Mongol power, and Kublai Khan conquered China.

Japan has never been invaded in historical times, but an attempt made by Kublai Khan to conquer it was successfully repulsed.
