revenge, he was powerless for any open enmity. Tekish's son, Muhammad II (1200–1220), annoyed at the actions of the caliph, set up a Shi'a Caliph to paralyse al-Nasir's spiritual power. Following up this act, he turned his army on Baghdad. In response, some medieval historians write that al-Nasir appealed to Genghis Khan, the rising Mongol chief, to check Muhammad's progress. This point is controversial, but it is likely that the caliph had some contacts to the non-Muslims Mongols. The caliph soon found Genghis Khan to be quite threatening.

The Caliph sent an army numbering 15,000 under his vizier Jalal al-Din 'Ubaidallah b.
