Temür, grandson of Kublai, is elected Khagan of the Mongols with the reigning title Oljeitu.

Öljeyitü Khan, born Temür, also known by his temple name as the Emperor Chengzong of Yuan, was the second emperor of the Yuan dynasty of China, ruling from 10 May 1294 to 10 February 1307. Apart from being the Emperor of China, he is considered as the sixth Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire. He was an able ruler of the Yuan dynasty, and his reign established the patterns of power for the next few decades.

Kublai Khan, also known by his temple name as the Emperor Shizu of Yuan and his regnal name Setsen Khan, was the founder and first emperor of the Mongol-led Yuan dynasty of China. He proclaimed the dynastic name "Great Yuan" in 1271, and ruled Yuan China until his death in 1294.

Khagan or Qaghan is a title of imperial rank in Turkic, Mongolic, and some other languages, equal to the status of emperor and someone who rules a khaganate (empire). The female equivalent is Khatun.
