Nizamiyya of Baghdad

The Nizamiyya of Baghdad or the Baghdad Nizamiyya, also known as the Nizamian college of Baghdad (Arabic: المدرسة النظامية في بغداد, romanized: al-Madrasa n-Niẓāmiyya fī Baġdād, lit.'the Nizamian school in Baghdad'), was one of the first Nizamiyyas, established in 1065 in Baghdad. The Nizamiyya of Baghdad was considered among the most important and prestigious educational institutions of the Abbasid era, alongside the Mustansiriyya Madrasa. It has been described as the "largest university of the Medieval world." The Nizamiyya school was completely Shafi'i. One of its requirements was that all teachers, preachers, and librarians be Shafi'i in jurisprudence and Ash'ari in theology. This school was home to prominent Shafi'i jurists including Abu Ishaq al-Shirazi, Ibn al-Sabbagh, Abu Sa'ad al-Mutawalli, Abu Hamid al-Ghazali, and al-Kiya al-Harrasi.
