Gün Temür Khan

Gün Temür (Гүнтөмөр; Mongolian script: ; ), regnal name Toqoqan Khan (Тогоон хаан; ), (1377–1402) was a khagan of the Northern Yuan dynasty, reigning from 1399 to 1402. Erdeniin Tobchi claimed that Gün Temür was the eldest son of Elbeg Nigülesügchi Khan, but records in Habib al-siyar and Zafarnama he as other Genghizid (maybe descendant of Ariq Böke ). His name, Gün Temür, means "Deep (intellectually) Iron" in the Mongolian language.

Reign
In 1402, Gün Temür was defeated by Gulichi (possibly with Arughtai), who killed him as a result. Gulichi later seizes the title Örüg Temür Khan. Several years later, Elbeg Nigülesügchi Khan's son Bunyashiri returned to Mongolia and succeed the throne, known as Öljei Temür Khan.
