Mahakorgis or Markorgis (Mongolian:  , Mongolian Language:   ; Chinese: ; 14481465) was a Mongol Khan of the Northern Yuan dynasty based in the Mongolian Plateau. Mahakorgis was given the title Ukegtu because he sat inside a cart during the battles. After that Samar taifu and Dogholon taishi of the seven Tumeds crowned the boy Khagan. The Tumeds reached their peak under the rule of Altan Khan (15071582) in the mid-16th century. They raided the Ming dynasty and attacked the Four Oirats. They defeated the Oirads and returned with plundered goods. Oirats (Mongolian: , Oirad, Mongolian pronunciation: [irt or , Oird; Kalmyk: ; in the past, also Eleuths) are the westernmost group of the Mongols whose ancestral home is in the Altai region of Siberia, Xinjiang and Western Mongolia.
