Eystein Glumra
Eystein Glumra(" Eystein the Noisy" or" Eystein the Clatterer"; Modern Norwegian" Øystein Glumra") also known as Eystein Ivarsson, was reputedly a petty king on the west coast of Norway, during the 9th Century.
The" Heimskringla" saga states that Eystein Glumra was the father of Rognvald Eysteinsson and Sigurd Eysteinsson:" The first earl in the Orkney Islands was called Sigurd, who was a son of Eystein Glumra, and brother of Ragnvald earl of More.
After Sigurd, his son Guthorm was earl for one year.
After him Torf- Einar, a son of Ragnvald, took the earldom, and was long earl, and was a man of great power".
According to the" Orkneyinga Saga", Eystein Glumra was the son of Ivar the jarl of Uplanders and grandson of Halfdan the Old.
" Orkneyinga Saga" also named Eystein Glumra as the father of Rognvald Eysteinsson:" Heiti, Gorr ’s son, was father of Sveiði the sea-king,[ who was] the father of Halfdan the old,[ who was] the father of Ivar the Uplanders ’ earl,[ who was] the father of Eystein the noisy,[ who was] the father of earl Rognvald the mighty and wise in council".

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.
