Fatih is a municipality (belediye) and district in Istanbul, Turkey that encompasses most of the peninsula coinciding with historic Constantinople. In 2009, the district of Eminönü, formerly a separate municipality located at the tip of the peninsula, was merged into Fatih. Fatih borders the Golden Horn to the north and the Sea of Marmara to the south, while the Western border is demarked by the Theodosian wall. The mayor is Mustafa Demir (AKP).
At present, Fatih contains areas including Aksaray, Fındıkzade, Çapa, and Vatan Caddesi that are more cosmopolitan than the extreme conservative image which the district has in the eyes of many people (because of the religious community of the Çarşamba quarter within the district.) With Eminönü, which was officially an area of the Fatih district until 1928, and with its historical Byzantine walls, conquered by Mehmed II, Fatih is the "real" Istanbul of the old times, before the recent enlargement of the city that began in the 19th century.
The area has become more and more crowded from the 1960s onwards, and a large portion of the middle class residents moved to the Anatolian side and other parts of the city. Fatih today is largely a working class district, but being a previously wealthy area, is well-resourced, with a more thoroughly established community than the relatively poorer residents of the newly built areas such as Bağcılar or Esenler to the west, which are almost entirely inhabited by post-1980s immigrants who came to the city in desperate circumstances. Fatih, at least, was built with some degree of central planning by the municipality.
Besides the Haliç University and the Kadir Has University, two different Faculty of Medicine campuses of Istanbul University (Çapa Faculty of Medicine and Cerrahpaşa Faculty of Medicine) are in Fatih. Moreover, since 1586, the Orthodox Christian Patriarchate of Constantinople has its headquarters in the relatively modest Church of St. George in the Fener district of Fatih.
