Töregene Khatun
During the reign of Ögedei, the Seljuks of Rum wanted friendship and gave money Chormaqan every year. Under Kaykhusraw II, however, the Mongols began to pressure the Sultan to go to Mongolia himself, give people whom he put in jail, and accept a Mongol darughachi. Mongol raids began in 1240. The Seljuk Sultan Kaykhusraw made a large army to meet them. The king of Cilician Armenia was required to give 1400 lances and the Greek Emperor of Nicaea 400 lances. Both rulers met the Sultan in Kayseri to talk. The Grand Komnenos of Trebizond gave 200 lances, while the young Ayyubid prince of Aleppo gave 1000 horsemen.In addition to these, Kaykhusraw told the Seljuq army and Turkmen cavalry, though both had been weakened by the Baba Ishak rebellion. However, Baiju and his Georgian helpers defeated them at the battle of Köse Dağ in 1243. After that battle, the Sultanate of Rum, the Empire of Trebizond and the Lesser Armenia quickly declared their allegiance one by one to the Mongol Empire ruled by Töregene Khatun.
