Zahir al-Din Nishapuri

Zahir al-Din Nishapuri (died c. 1184) was a Persian writer and the author of the Saljuq-nama ("Book of Seljuk [Empire]"), an important source regarding the history of the Seljuk Empire. The life of Nishapuri is obscure; he is reported to have served as tutor of the previous Seljuk sultans, Ghiyath ad-Din Mas'ud ((r. 1134 – 1152)) and Arslan ibn Tughril (r. 1153). Although the Saljuq-nama is now lost, it was used as the primary source of the contemporary Persian historian Muhammad ibn Ali Rawandi.
