The Year 623 
This chapter deals with the events of the year 623 (1226) in the lifetime of Ibn al-Athir. It gives an account of Jalal al-Din, son of Khwarazm Shah, conquering the city of Tiflis from the Georgians during Rabi‘ I. Jalal al-Din confronted the Georgians and set ambushes for them in several places. Battle was joined and eventually the Georgians fled in rout, with every man for himself. in Armenia the Georgians entered the town of Arjish and took Kars and other places. They besieged Khilat. Were it not that God (glory be to Him) showed favour to the Muslims through the capture of Iwani, the commander of the Georgian troops, they would have seized it. The chapter also describes the expedition of Muzaffar al-Din, lord of Irbil, to Mosul and his withdrawal.
