Wikipedia Overview

The Ildegizids, Eldiguzids or Ildenizids, also known as Atabegs of Azerbaijan, were an Atabegate that broke off from the Seljuk Empire, and a Sunni Muslim Turkic dynasty, which controlled most of northwestern Persia, eastern Transcaucasia, including Arran, most of Iranian Azerbaijan, and Jibal. At their maximum extent, the territory under their control, roughly corresponds to most of north-western Iran, most of the regions of modern Azerbaijan and smaller portions in modern Armenia, Turkey and Iraq. 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.
