The Islamic Golden Age fostered early studies in Islamic psychology and psychiatry, with many scholars writing about mental disorders. The Persian physician Muhammad ibn Zakariya al-Razi, also known as "Rhazes", wrote texts about psychiatric conditions in the 9th century. As chief physician of a hospital in Baghdad, he was also the director of one of the first psychiatric wards in the world. Two of his works in particular, "El-Mansuri" and "Al-Hawi", provide descriptions and treatments for mental illnesses.
