This study examines Khwaja Nizam al-Mulk Tusi’s political thought in light of Spragens’ crisis theory. It hypothesizes that the internal logic of his political thought is grounded in two traditions: ancient Iranian and Islamic political thought. Employing a descriptive-analytical method, the study analyzes Siyasatnama and Nizam al-Mulk Tusi’s political thought. The findings indicate that he identified the fundamental crisis as the Turks’ unfamiliarity with the art of governance and the administration of society, together with what he regarded as religious deviation. He traced the roots of this crisis to the tribal traditions of the Seljuk Turkmens, their limited knowledge of governance, and the spread of Ismaili, Batiniyya, and Qarmatian doctrines and ideas, which he considered religiously heterodox. In his view, the remedy lay in establishing an absolute yet just government founded on Sunni Islam. Additional measures he proposed included excluding those he regarded as religiously heterodox from government and establishing Nizamiyya madrasas. His political ideal thus represented a synthesis of the governing traditions of ancient Iran and the Islamic period.
