Kublai Khan or Khubilai Khan or "the last of the great Khans" 1215–1294 (also spelled as Kubilay Han in Turkic), was a Mongol military leader. He was Khan (1260–1294) of the Mongol Empire as well as the founder and the first Emperor (1279–1294) of the Chinese Yuan Dynasty.

Born the second son of Tolui and Sorghaghtani Beki and the grandson of Genghis Khan, he succeeded his brother Möngke in 1260. Kublai Khan's brother, Hulagu, conquered Persia and founded the Ilkhanate. Kublai also had a nephew named Kaidu, who died in 1301.

Kublai was a favorite of his grandfather Genghis Khan. As a youth, he studied Chinese culture and became enamored with it. In 1251, his elder brother Mongke became Khan of the Mongol Empire, and Kublai became the governor of Southern territories of Mongol Empire. During his years as governor, Kublai managed his territory well, boosting the agricultural output of Henan and increasingcial welfare spendings after receiving Xi'an. These acts received great acclaim from Chinese warlords and were essential to the building of Yuan Dynasty.

In 1253, Kublai was ordered to attack Yunnan. He eventually attacked and destroyed the Kingdom of Dali. In 1258, Mongke put Kublai in command of the Eastern Army and summoned him to assist with the attacks on Sichuan and Yunnan. Before Kublai could arrive in 1259, words had reached him that Mongke had died. Despite his brother's death, Kublai continued to attack Wuhan. Soon thereafter, Kublai receieved news that his younger brother had usurped power. Kublai quickly reached a peace agreement with Song troops and rode back north to the Mongolian plains.

Both his brother and Kublai crowned themselves Khan in 1260, and the two brothers battled for three years before Kublai finally won. However, during this civil war, Yizhou governor Li revolted against Mongol rule, but was swiftly crushed by Kublai Khan. This incident caused Kublai's distrust of ethnic Hans, and after he became emperor, Kublai instituted many anti-Han laws, such as banning the titles of and tithes to Han Chinese warlords

The empire was separated into four khanates, each ruled by a separate khan and overseen by the Great Khan. The Kipchak Khanate (also called the Golden Horde) ruled Russia; the Ilkhanate ruled the Middle East, the Chagatai Khanate ruled over western Asia, and the Great Khanate controlled Mongolia and eventually China. The empire reached its greatest extent under Kublai with his conquest of China, and completed by his final victory over the Song Dynasty in 1279.

As emperor of Yuan Dynasty, Kublai Khan worked to minimize the infleunces of regional lords who had held immense power before and during the Song Dynasty. His mistrust of ethnic Han Chinese caused him to hire other ethnic group members as officials more often than Han Chinese.

At the Eighth Year of Zhiyuan(1271), Kublai Khan officially declared the creation of the Yuan Dynasty, and proclaimed the capital to be at Dai Du (Beijing, China) in the following year. To unify China, Kublai Khan began a massive offense against the remnants of Southern Song Dynasty in the 11th year of Zhiyuan, and finally destroyed the Song Dynasty in the 16th year of Zhiyuan, unifying the country at last.

He ruled better than his predecessors, promoting economic growth with the rebuilding of the Grand Canal, repairing public buildings, and extending highways. However, Kublai Khan's domestic policy also included some aspects of the old Mongol living traditions, and as Kublai Khan continued his reign, these traditions would clash more and more frequently with traditional Chinese economical and social culture.

He also introduced paper currency although eventually a lack of fiscal discipline and inflation turned this into an economic disaster. He encouraged Chinese arts and demonstrated religious tolerance, except in regards to Taoism. His capital was at Beijing (then Cambuluc or Dadu 大都 lit. big capital). The empire was visited by several Europeans, notably Marco Polo in the 1270s who may have seen the summer capital in Shangdu (上都 lit. upper capital or Xanadu).

He conquered Dali (Yunnan) and Goryeo (Korea). Under pressure from his Mongolian advisors, Kublai attempted to conquer Japan, Myanmar, Vietnam and Indonesia. All these failed attempts, costly expeditions, along with the introduction of paper currency caused inflation. However, Kublai Khan also forced warlords from the Northwest and Northeast to capitulate, ensuring stability for those regions. Kublai Khan died in the 31st year of Zhiyuan. (1294)

Kublai Khan twice attempted to invade Japan in search of gold; however, both times the Samurai resisted greatly and the weather tore the fleets apart. The first attempted invasion was in 1274 with a fleet of 900 ships. The second invasion was in 1281 with a fleet of over 1,170 large war junks, each close to 240 feet long. Dr. Kenzo Hayashida, the marine archaeologist who discovered the wreckage of the second invading fleet off the western coast of Takashima, headed their excavation. The findings strongly indicate that Kublai Khan rushed to conquer China and attempted to construct the large fleet in a year (a task that should have taken up to 5 years), which forced the Chinese — who already hated their conquerors — to use any available ships, particularly river boats, as the basis for Khan's fleet. Khan also used captured Chinese river boats in his invasion fleet. Had Kublai used ocean going ships, which have a curved keel to prevent capsizing, his navy may have survived the storm and made it to invade Japan as originally intended.

John Pearson, author of Kublai Khan (2005), writes, "The cost of these defeats led the Khan to devalue the central currency, further exacerbating growing inflation. He also increased tax assessments. These economic problems lead to growing resentment of the Mongols, who paid no taxes, among the Chinese populace." David Nicole writes in The Mongol Conquerors that "these disastrous defeats shattered the myth of Mongol invincibility throughout Asia." He also wrote that Kublai Khan was determined to mount a third invasion, despite the horrendous cost to the economy and to his and Mongol prestige of the first two defeats, and only his death prevented such a third attempt, despite the unanimous agreement of his advisors against such an attempt."

In early 2006, marine archaeologists determined that previous theories that Kublai's fleet was made up entirely of ships that came from river boats was found to be weakened as evidence of keel usage began to show up in recent discoveries. One current theory that has yet to be found false is the idea that the new Mongol technology of explosives (grenade-like weapons) may have backfired, potentially from inexperienced engineering, when an attack on Japan would have begun.
