Jebe was one of the most prominent Noyans (generals) of Genghis Khan. He belonged to the Besud clan, part of the Taichud tribe, which was under Targudai Khiriltug's leadership at the time of Genghis Khan. Although Jebe was originally an enemy soldier, Genghis recruited him and turned him into one of his greatest generals. Jebe played an important role in helping to expand the territory of Genghis's empire. Despite his importance, there are relatively few sources or biographies about his life. Jebe has been described as "the greatest cavalry general in history" for his unorthodox and daring maneuvers.
