Jalayirid Sultanate

The Jalayirid Sultanate was a Persianate Mongol Jalayir dynasty which ruled over Iraq and western Persia after the breakup of the Mongol khanate of Persia in the 1330s. It lasted about fifty years, until disrupted by Timur's conquests and the revolts of the Kara Koyunlu ("Black Sheep") Turkmen. After Timur's death in 1405, there was a brief attempt to re-establish the sultanate in southern Iraq and Khuzistan. The Jalayirids were finally eliminated by the Kara Koyunlu in 1432.

The Jalayirid administration was modeled after Ilkhanate protocols, with documents in Persian and Mongolian. Its diplomatic correspondence also copied the Ilkhanate's, using a red ink square seal with Islamic phrases in Arabic.
