Baiju

Timeline

1. 1242–1243Tabriz–Erzurum · Eastern AnatoliaAfter Chüchü's death, Baiju was ordered to take command of the Mongol garrisons in Persia, Azerbaijan, and on the Anatolian frontier. He reorganized Chüchü's former troops, used Erzurum as a forward base, and prepared a decisive offensive against the Sultanate of Rum, which refused to submit.
2. 1243Köse Dağ · Erzincan ProvinceBaiju led his army to a crushing victory over the coalition of Kaykhusraw II, sultan of Rum, near Köse Dağ. The battle left the Seljuk regime in Asia Minor a mere shell; the Sultanate of Rum was forced to submit and pay tribute, and Baiju established Mongol suzerainty over Anatolia.
3. 1244–1250Erzurum · ErzurumAfter Köse Dağ, Baiju was long stationed at Erzurum, maintaining control over Anatolian beys and sultanates through supporting vassals, collecting tribute, and military intimidation. During the change of khans in the late 1240s he still held the western frontier, until Hulegu's western expeditionary army marched into Western Asia.
