A jasagh (засаг, or засаг ноён; lit. Power, Authority) was the head of a Mongolbanner or khoshun during the Qing dynasty (1644-1911) and Boghda Khanate of Mongolia. The term is rendered zhasake (札薩克) in contemporary Chinese documents. The position was held by hereditary succession by certain Mongol princes, most of whom were descendants of Genghis Khan. The princes who did not serve as Jasagh were known as sula (сул - empty vacant free, loose) or hohi taiji (хохь тайж).
