Işık University (Turkish: Işık Üniversitesi) is a private university located in Istanbul, Turkey. The university is a part of the Feyziye Schools Foundation which was established in Thessaloniki in 1885. The history of (Feyziye Schools Foundation Işık Schools) Feyziye Mektepleri Vakfi Isik Okulları began on 14 December 1885 in the city of Thessaloniki, one of the most dynamic cities in the days of the Ottoman Empire, with the establishment of Feyz-i Sıbyan School. The school has gone through enormous expansion, including Şemsi Efendi School - the school where Mustafa Kemal Atatürk received his initial education. Following the Balkan Wars when Thessaloniki became part of Greece, Feyziye School moved its operations to Istanbul and continued its pursuit in educational excellence in Nişantaşı Naciye Sultan Mansion. In 1935 during the 50th anniversary of the School, the name was changed from "Feyziye" to "Işık" (which means "light" in Turkish) with the blessings of Mustafa Kemal Atatürk. In 1986, the Foundation completed its Maslak campus, in order to meet the need for educational institutions.
