Although the ruling Tayichiud clan was destroyed by Genghis, their descendants, who surrendered, achieved fame in parts of the Mongol Empire. Jebe (born Jurgaadai), who struck the final blow to the Jurchens in Manchuria in 1219 and defeated Kypchaks and their European allies at the battle of Kalka in 1223, was from Besud clan of Tayichiud. Baiju, the commander of the Tammachi in Persia, was also from the Besud clan of the Tayichud. Chilaun, one of Genghis Khan's four close companions, was from the Suldus, a sub-clan of the Tayichiud. His descendant Chupan reached the peak of his career during the reign of IlkhanAbu Said and was given the title of chief commander of all Mongol Khanates by the court of the Yuan Dynasty in 1327. In the Chagatai Khanate, another aristocrat, Buyan Suldus, overthrew Qara'unas in Transoxiana in 1359 but was executed by Chagatai Khan Tughluq Temur in 1362.
