# Istanbul University

Istanbul University, also known as University of Istanbul (Turkish: İstanbul Üniversitesi), is a public research university located in Istanbul, Turkey. Founded by Mehmed II on May 30, 1453, a day after the conquest of Constantinople by the Turks, it was reformed as the first Ottoman higher education institution influenced by European approaches. The successor institution, which has been operating under its current name since 1933, is the first university in modern Turkey.
The university has 58,809 undergraduate, graduate, and doctoral students studying in 112 academic units, including faculties, institutes, colleges, and vocational schools at 9 campuses. The main campus is adjacent to Beyazıt Square in Fatih, the capital district of the province, on the European side of the city.
Istanbul University alumni include Nobel Prize in Chemistry winner Aziz Sancar and Nobel Prize in Literature winner Orhan Pamuk, as well as President of Turkey Abdullah Gül, six Prime Ministers of Turkey, including Suat Hayri Ürgüplü, Sadi Irmak, Nihat Erim, Refik Saydam, Naim Talu, Yıldırım Akbulut, and the current mayor of Istanbul Ekrem İmamoğlu. The alumni also include the longest-serving President of Israel Yitzhak Ben-Zvi, as well as David Ben-Gurion and Moshe Sharett, who both served as Prime Ministers of Israel.

## History

The origins of Istanbul University date back to 1453, when it was founded by Ottoman Sultan Mehmed II as a school of philosophy, medicine, law and letters. The University of Constantinople, established in 425 CE by the Eastern Roman emperor Theodosius II as the Pandidacterium, later became known as the Phanar Greek Orthodox College after the Fall of Constantinople in 1453. In the early stages, Istanbul University also functioned as a medrese, an Islamic theological school. This madrasa is regarded as the precursor to the Darülfünûn, a technical institute or university (lit. House of Natural Sciences), which evolved into Istanbul University in 1933. Education in various sciences and fields, including medicine, mathematics, astronomy, cartography, geography, history, philosophy, religion, literature, philology, and law, became available and, until the 19th century, played a key role in educating the ruling cadres of Ottoman society. However, when the medreses were no longer able to meet the needs of the time, a restructuring process began, leading to the establishment of Darülfünûn, the core of Istanbul University.
An institution of higher education named the Darülfünûn-u Osmanî (lit. the Ottoman Polytechnic Institute) was created in 1863, but suppressed in 1871. Its first rector was Hasan Tahsini, regarded as one of the most important Ottoman scholars of the 19th century. In 1874 the Darülfünûn-u Sultanî (lit. the Royal College of Natural Sciences, French: Université Impériale Ottoman) began offering law classes in French, but was closed in 1881.
The Imperial College of Sciences, later known as Darülfünûn-u Şahâne, was reestablished in 1900 with departments in theology, arts, mathematics, science, and philology. In 1924, the faculties of law, medicine, arts and sciences were established in İstanbul Darülfünûnu, as the university was now called. Islamic theology was added in 1925, but in 1933 the university was reorganized without the latter.
The first modern applied physics courses were offered at the Darülfünûn on 31 December 1863, marking the beginning of a new era. On 20 February 1870, the school was renamed Darülfünûn-u Osmanî (lit. the Ottoman House of Multiple Sciences) and reorganized to meet the needs of modern sciences and technologies. Starting in 1874, some classes in literature, law, and applied sciences were held at the Lycée de Galatasaray, continuing regularly until 1881. On 1 September 1900, the school was renamed and reorganized as Darülfünûn-u Şahâne (lit. the Royal Polytechnic Institute), offering courses in mathematics, literature, and theology. On 20 April 1912, the school was renamed İstanbul Darülfünûnu, with an expanded course offering and a modernized curriculum. The School of Medicine, Law, Applied Sciences, Literature, and Theology were established.
On 21 April 1924, the Republic of Turkey recognized İstanbul Darülfünûnu as a state institution. On 7 October 1925, its administrative autonomy was established, and the schools, which had been part of the old medrese system, became modern faculties. The Darülfünûn then consisted of five faculties: medicine, law, letters, theology, and science. The professors were granted academic freedom as outlined in Article 2 of Law 493. On 1 August 1933, İstanbul Darülfünûnu was reorganized as İstanbul Üniversitesi (lit. Istanbul University) following the educational reforms of Mustafa Kemal Atatürk. Classes officially began on 1 November 1933.
Before World War II, many German scientists, particularly those from fields such as medicine, natural sciences, and humanities, were forced to flee Germany due to pressure on anti-Nazi scholars and artists, many of whom were of Jewish origin. A significant number of these emigrants found refuge at Istanbul University, where they contributed to the growth of academic programs and research, enhancing the university's intellectual environment and fostering scientific efforts in Turkey.
In March 2025, the university revoked the degrees of politician and opposition leader Ekrem Imamoglu and 27 other graduates – citing procedural irregularities – just days before Immamoglu was due to announce his candidacy for the presidency, raising questions of political interference, since the role requires a higher education degree.

## Campus

The university comprises seventeen faculties spread across five campuses. The main campus being on Beyazıt Square, which was originally built by Constantine the Great as the Forum Tauri and was later enlarged by Theodosius the Great as the Forum of Theodosius during the Roman period. Some Roman and Byzantine ruins are still visible on the grounds.
The building stands on the site of the Old Palace, the first palace built by the Ottoman Turks in Istanbul. Following the establishment of the Republic in 1923, the Ministry of War, like other ministries, relocated to Ankara, and the building was handed over to Darülfünun, the first and only university of the Ottoman Empire.
The current main building, designed by French architect Bourgerois, was completed in 1865-1866. In 1879, it began serving as the Ottoman Empire's Ministry of War. The Blue Hall and Pink Hall, located on the building's second floor, are adorned in an orientalist decorative style, featuring ceiling and wall ornamentations that reflect the overall aesthetic of the structure. The room currently used as the Rector's Office was originally the office of the Minister of War during the Ottoman Empire. The office also contains the desk of Enver Pasha, who served as the Minister of War from 1914 to 1918. The "Kılıçlık Hall," which is used for academic meetings today, was originally the venue for sword-donning ceremonies for officers within the Ministry of War during the Ottoman Empire. Before holding meetings in the Kılıçlık Hall, officers would use the area on the right side of the hall to place their swords, hang their coats, and perform ablutions.
The building, which was damaged in an earthquake in 1894, was restored by Italian architect Raimondo D’Aronco. In 1950, it was again restored by Ekrem Hakkı Ayverdi. The Rectorate Building has undergone several renovations over the years, with the most recent restoration, including façade and marble cleaning, taking place in 1998. The main gate was depicted on the reverse of the Turkish 500 lira banknotes of 1971–1984.
The building housing the Rare Books Library, designed by Kemaleddin Bey in 1913, is home to a collection of approximately 93,000 volumes, including printed and manuscript books, journals, newspapers, maps, plans, and notes in Turkish, Arabic, Persian, Greek and Latin. The collection also includes 911 albums known as the Abdülhamid II Collection, which contain 36,585 photographs. Additionally, the library holds the collections of prominent figures in Turkish politics and intellectual history, such as Zakirbaşı Hüseyin Halis Efendi, Hasan Rıza Pasha, Grand Vizier İbrahim Hakkı Pasha, Sheikh-ul-Islam Pirizade Mehmet Sahip Molla, and İbnülemin Mahmut Kemal İnal. In 1925, the collection of the Yıldız Palace Library was transferred to the Rare Books Library.
