Hasanpaşa, Kadıköy

The current neighborhood of Hasanpaşa is within the limits of ancient Chalcedon, with the city's cemetery and hippodrome probably located in this area. During Byzantine times, the area was known for its vineyards, orchards, and vegetable gardens and for its imperial summer palaces.^[7]

During the 17th century, in Ottoman times, the area was the property of Kızlarağası Mısırlı Osman Ağa, but was nationalized by Murat IV in 1630. In 1800, it became the property of Selim III, was used as a hunting ground in the time of Mahmut II, and was given to Kapıcıbaşı Hüsameddin Efendi in the time of Abdülmecit I (r. 1839-1861). Hüsameddin Efendi's heirs divided the land into lots and began selling it. The area, however, remained sparsely settled, covered mostly in vineyards, gardens, and meadows. In 1876, some Romanian and Bulgarian refugees from the Russian-Ottoman War were settled in the İkbaliye area of current Hasanpaşa, but even then only 8-10 houses.^[8]

A large gasworks began operation in the area in 1892. After the construction of the Hasan Paşa Mosque, more Turks began to settle in the area, and in 1900 the neighborhood was officially separated from the Osman Ağa neighborhood and called the Kaptan Hasan Paşa neighborhood. Because of the gasworks, the neighborhood was also sometimes called Gazhane. By the 1950s, sewage from the crowded neighborhood and discharge from the gasworks had severely polluted Kurbağalı Stream.^[9]
