نظام الملك
Nizam al-Mulk left a great mark on organization of the Seljuk governmental bodies and hence the title Nizam al-Mulk which translates as "Order of the Realm." He bridged political gaps among the Abbasids, the Seljuks, and their various rivals such as the Fatimids. The Seljuk military was heavily mixed of different ethnicity, including Turks, Armenians, Greeks, Arabs, and Slavs. Nizam, however, favored Iranian soldiers, such as the Dailamites, Khorasanis, and the Shabankara. He also favored non-Iranian soldiers such as the Georgians.
