 Meanwhile , leaders of the Kilab continued to hold the title of amir al @-@ ʿarab after the Ayyubid conquest of Aleppo in 1182 . As a result , Haditha 's jurisdiction initially did not extend to the Aleppo region ( northern Syria ) . However , during the latter half of az @-@ Zahir Ghazi ( r . 1193 – 1216 ) of Aleppo 's reign , the Kilab were brought under Haditha 's authority and were stripped of the amir al @-@ ʿarab title . According to medieval Arab historian Ibn al @-@ Adim ( d . 1262 ) , the Kilab 's status was downgraded because of the growing power of the Tayy clans , while al @-@ Hamdani asserts that the numerically @-@ superior Kilab were weakened by a divided leadership . Following the extension of Haditha 's jurisdiction to their traditional territory , some of the Kilab migrated north to Anatolia , while those who remained became allies of Haditha 's Al Fadl clan .
