The Nizamiyyah (Persian: nZmyh, Arabic: lnZmy@) are a series of medieval higher education institutes founded in Iran in the eleventh century by Khwaja Nizam al-Mulk. His name inspired the name Nizamiyyah. The Nizamiyyah were particularly renowned for their teaching and research in the fields of medicine, science, and philosophy. They play an important role in the history of psychology as one of the first institutions to experiment with this new discipline. The Nizamiyyah school was founded by Khwaja Nizam al-Mulk, a Persian physician who lived in India between 1092 and 1162. He is regarded as one of the most important scientists of his time and is also known for establishing medical schools in universities worldwide. Khwaja Nizam established several universities in different cities of India. His most famous institution is located in Baghdad where it was known as "College of Physicians".
