But who was the "Nur al - Din Atabeg" featured on the obverse side of most coins of this type , and why was he also recognized? He is not further identified on the coins , but the most logical candidate would appear to be Nur al - Din Arslan Shah I , the Zengid Atabeg of Mosul ( 589-607 / 1193-1210 ) , the only atabeg with the laqab Nur al - Din known to have been active at that time . This identification was first advanced by Mitchiner in 1977 and was repeated by Hennequin in the Paris catalog.

Why the Artuqid Yuluq Arslan of Mardin should put his rival's name on his coins is not altogether clear
The rise of the Zangids halted the Artuqids' expansionist plans, and they had to become vassals of Nur al-Din. Then the Ayyubids whittled their power down further, and they lost Hisn Kayfa, Amid and Mayyafariqin to them. In the early thirteenth century, they were for a time vassals of the Rum Seljuqs and of the Khwarazm Shah Jalal al-Dln Mengiibirti. Eventually, only the Mardln line survived, with Qara Arslan submitting to the Mongol II Khan Hulegu.
