As emperor, Kublai Khan built a great empire that grew wealthy from trade, but he failed to expand his power beyond China.
The Sung dynasty ruled southern China.
The Mongols wanted their rich farmland and wealth.
The Mongols repeatedly tried-- and failed--to conquer the Sung dynasty.

When Kublai Khan took power, he first squashed rebellions and defeated enemies in North China.
The Mongols continually fail to defeat the Sung dynasty before Kublai Khan's win because the Sung army had many soldiers.
