In what year was the Eldeniz state formed?

The state of Ildegizids or Atabeks was formed in 1136 on the territory of Azerbaijan, parts of Iran and Arran. This power was formed by the Mamluks on the ruins of the Seljuk monarchy. Atabek Shamseddin Ildeniz is considered the founder. The collapse of the state of the Atabeks began to occur less than a hundred years later – in 1220 during the Mongol campaign of Jebe and Subutai. The last atabek ruler, Uzbek, concluded an agreement with the Mongols, paid the ransom and provided horses and provisions. During the reign of the Atabeks, the Persian culture and language spread in the state.
