The Arab kings appear as Kings and the lands are Kingdom instead of Sultan/Sultanate. So does the Abbasid Kaliph appear as King of Abbasids. If there's a chance the title should be changed to Kaliph and the his reign changed to Kaliphate of the Sunni. Abbasid was only the name of the dynasty. And by 1066 there was only the title left, all of their lands (including capital city of Bagdad) were granted to Seljuks.
