 Down to the death in war 1194 of Toghril b. Arslan, last of the Great Seljuq rulers of Iraq and Persia, the Ildenizids ruled as theoretical subordinates of the Sultans,
acknowledging this dependence on their coins almost down to the end of the Seljuqs.Thereafter, they were in effect an independent dynasty, until the westward expansion of the Mongols and the Khwarazm-Shahs weakened and then brought the line to its close.Atabeg (literally means ""fatherly lord"" in Turkic) was the title conferred upon the Turkic officers who served as guardians of minor Seljuq rulers.
