Analysis of information sources in references of the Wikipedia article "Artuq Arslan" in English language version.
In 1229 Jalal al-Din, the exiled Khwarazm Shah, began again to threaten the Ayyubids and their Turkoman alliesfrom his base in Armenia. The allies mounted a counter-offensive and, after several battles, defeated Jalal al-Din decisively late in 1230. Artuq Arslan supported the Ayyubids in this crisis, while the Artuqid cousin Rukn al-Din, ruler of Hisn Kayfa and Amid, made common cause with the Khwarazmshah.
