Biblical Magi
There was a tradition that the Naimans and their Christian relatives, the Keraites, descended from the Biblical Magi. The commander of the Mongol army that invaded Syria in 1259, Kitbuqa, was a Naiman: he is recorded to have "loved and honoured the Christians, because he was of the lineage of the Three Kings of Orient who came to Bethlehem to adore the nativity of Our Lord". However, Kitbuqa was slain and his army decisively defeated at the Battle of Ain Jalut, ensuring continued Muslim hegemony over the Levant.
