Taj al-Din Husayn

Taj al-Din Husayn (died 1277) was a son of the Seljuk vizier Sahib Ata Fakhr al-Din Ali. In 1275 the Ilkhan Abaqa granted Karahisar-i Sahib (Afyonkarahisar) and its district to Husayn and his brother Nusrat al-Din Hasan as a holding, establishing the Sahib Ataid beylik under their joint rule.

In 1277 the brothers took the field against the Karamanid Mehmed Bey, who with the pretender Cimri had seized Konya, and both were killed at the Battle of Değirmençayı.
