Seljuk Empire

Abu Hamid al-Ghazali (1058–1111 CE) was among the most influential thinkers in Islamic history. His Ihya Ulum al-Din synthesized law, theology, and mysticism, while his critique of Aristotelian rationalism and account of spiritual crisis remain landmarks of medieval thought.

Nizam al-Mulk (1018-1092 CE) was one of the greatest statesmen in Islamic history, serving as vizier to the Seljuk sultans. He established the Nizamiyya schools that revolutionized Islamic education and wrote the influential Siyasatnama on political philosophy.

The Seljuk Empire (1037-1194 CE) was a powerful Turkish-Sunni dynasty that dominated the Middle East and Anatolia, defeated the Byzantine Empire at Manzikert, established Turkish power in Anatolia, and patronized the famous Nizamiyya schools.
