End of the Seljuk Empire in Iran

1194

Tughrul III, the last Seljuk sultan of the west, was killed in battle against the Khwarazmshah Tekish at Rey, south of modern Tehran. The Seljuk line that had ruled Persia, Mesopotamia, and Anatolia for a century and a half was extinct. The Khwarazmian empire filled the vacuum. The Seljuk collapse removed the last established dynasty between the Mongols and the Islamic heartlands, leaving the region fatally fragmented.
