Kitbuqa Noyan (died 1260), also spelled Kitbogha, Kitboga, or Ketbugha, was an Eastern Christian of the Naimans,[1] a group that was subservient to the Mongol Empire. He was a lieutenant and confidant of the Mongol Ilkhan Hulagu, assisting him in his conquests in the Middle East including the sack of Baghdad in 1258. When Hulagu took the bulk of his forces back with him to attend a ceremony in Mongolia, Kitbuqa was left in control of Syria, and was responsible for further Mongol raids southwards towards the Mamluk Sultanate based in Cairo. He was killed in 1260 at the Battle of Ain Jalut, which was the first major loss of the Mongolian advances and halted their expansion into Arabia and Europe.
