Kublai Khan
Kublai  was the fifth Khagan (Great Khan) of the Mongol Empire ("Ikh Mongol Uls"), reigning from 1260 to 1294
(although after the division of the empire this was a nominal position).
He also founded the Yuan dynasty in China as a conquest dynasty in 1271, and ruled as the first Yuan emperor until his death in 1294.
Kublai was the fourth son of Tolui (his second son with Sorghaghtani Beki) and a grandson of Genghis Khan.
He succeeded his older brother Möngke as Khagan in 1260, but had to defeat his younger brother Ariq Böke in the Toluid Civil War lasting until 1264.
This episode marked the beginning of disunity in the empire.
Kublai's real power was limited to China and Mongolia, though as Khagan he still had influence in the Ilkhanate and, to a significantly lesser degree, in the Golden Horde.
If one counts the Mongol Empire at that time as a whole, his realm reached from the Pacific Ocean to the Black Sea, from Siberia to what is now Afghanistan.
In 1271, Kublai established the Yuan dynasty, which ruled over present-day Mongolia, China, Korea, and some adjacent areas, and assumed the role of Emperor of China.
By 1279, the Mongol conquest of the Song dynasty was completed and Kublai became the first non-Han emperor to conquer all of China.
The imperial portrait of Kublai was part of an album of the portraits of Yuan emperors and empresses, now in the collection of the National Palace Museum in Taipei.
White, the color of the royal costume of Kublai, was the imperial color of the Yuan dynasty.

In the next year, he was dispatched to conquer Champa.
He demanded from Đại Việt (mordern Vietnam) a route to Champa, which would trap the Champan army from both north and south, but it was rejected by retired emperor Trần Thánh Tông, whom was the "de facto" ruler of Đại Việt.
As a result, Toghon decided to attack Đại Việt.
At first he won several victories and captured Thăng Long, the capital of Đại Việt.
Trần Thánh Tông had to offer princess An Tư to him to slow down the pace of the Mongol army.
Later he was defeated by Trần Hưng Đạo and fled back to Huguang province.
In 1287, he invaded Vietnam again, but, the Mongol Navy was overwhelmed by Trần dynasty in Bạch Đằng river, and he retreated.
This ashamed his father who no longer wished to see him again.
He moved to Yangzhou in 1291, where he died 10 years later.
