Jalal al-Din continued devastating one or another section of Armenia until 1230, when he was decisively beaten near Erzinjan by a united force composed of troops of Malik Ashraf of Khlat, the Seljuk sultan of Rum, Cilician Armenian, and Crusader detachments. Jalal was murdered the next year by a Kurdish peasant. His raids and devastations had lasted seven years.
Tughril, who ruled at Erzurum from 589 to 618/1192–1221, was allotted Elbistan under the original division by Kılıç Arslan II (Cahen 1968: 111), but was then installed at Erzurum when the latter was captured from the Saltukids at the beginning of the thirteeth century. But he broke away from the Seljuk state in 608/1211-12. His son Rukn al-Din Jahan Shah was finally defeated, and Erzurum annexed to the Seljuk state, in 1230, when the Khwarazmshah, Jalal al-Din, with whom Jahan Shah had temporarily allied, was defeated at the battle of Yassı Çimen.
