After the death of the governor of Jerusalem, Artuk Bey, in 1091, and following the Fatimid attack on the holy city, his children Sokman and Ilgazi left Bayt al-Maqdis. Sokman captured Hasankeyf, Mayyafariqin (Silvan) and Amid (Diyarbakır) in 1101 and established the first Artuqid Principality. Najm al-Din Ilghazi conquered Mardin in 1108 and declared it the capital of the Principality. With the conquest of Aleppo and Harput, the principality that would last 307 years was established. Ilghazi and his nephew Belek Ghazi became famous for fighting against the Crusaders. While they were busy settling in the conquered lands and fighting the Crusaders, the Artuqids founded in 1123 the Amin al-Din Complex, the first in Turkish history. The complex included a mosque, a madrasah, a hospital, lodges, a summer prayer space, a bath, a fountain and a special water well. Its construction was initiated by Amin al-Din Sokman, the founder of the Artuqid Principality, and was completed after his death by his brother Najm al-Din Ilghazi. It became famous during the period when it was used as a hospital. Different methods were employed in the hospital than those adopted in the Muslim World. While it was designed as a medical school/ madrasah and hospital where applied knowledge was instructed in its open courtyards, the bath section architecture, herbal medicine, the outdoors and water therapies were also used as treatments. It was used as a hospital until the 19th century based on archival documents from the time. The hospital, which was famous for its treatment methods and staff since its establishment, has contributed to the urban economy by attracting significant numbers of patients from other provinces, especially Mosul, and those injured in the Crusades.
