The history of Istanbul University dates back to the conquest of Istanbul by Sultan Mehmet II in 1453. Shortly after the conquest, Mehmet II founded a number of educational institutions, including the Medrese of Fatih Sultan Mehmet, which is considered to be the predecessor of Istanbul University.
The Medrese of Fatih Sultan Mehmet was a multidisciplinary institution that offered instruction in a variety of subjects, including Islamic theology, law, medicine, and mathematics. The medrese was open to students of all backgrounds, and it quickly became one of the most prestigious educational institutions in the Ottoman Empire.
In the centuries that followed, the Medrese of Fatih Sultan Mehmet underwent a number of reforms and expansions. In 1846, it was reorganized as the Darülfünun, or House of Multiple Sciences, which was the first Ottoman higher education institution based on European traditions.
The Darülfünun continued to grow and develop throughout the late 19th and early 20th centuries. In 1933, it was renamed Istanbul University, and it became the first and only university of the Republic of Turkey.
Istanbul University is ranked as the #7 top university in Turkey during 2025.
