Ebuskun served as regent for the Chagatai Khanate from 1242 until 1246 during the minority of her son Qara Hülëgü.[1]
She was the spouse of Mö'etüken, eldest son of Chagatai Khan and grandson of Genghis Khan.[2] She became a widow in 1221.[3]
When her father-in-law Chagatai died in 1242, her son inherited the throne. Since he was a minor, she became his regent, a role she fulfilled for four years.[4]
She lost power when the new grand khan Güyük Khan replaced her son Qara Hülëgü with Yesü Möngke. Within a few years, however, Kuyuk died, and Mongke raised Hülëgü and Ebuskun to their former positions. Shortly afterwards, Hülëgü also died; after this point, Ebuskun is no longer mentioned. Hülëgü's throne was passed to his wife, Organah Khatun.
