Beginning several centuries ago, a number of Africans, usually via Zanzibar as Zanj and from places such as Niger, Saudi Arabia, Libya, Kenya and Sudan, came to the Ottoman Empire settled by the Dalaman, Menderes and Gediz valleys, Manavgat, and Çukurova. African quarters of 19th-century İzmir, including Sabırtaşı, Dolapkuyu, Tamaşalık, İkiçeşmelik, and Ballıkuyu, are mentioned in contemporary records. Due to the slave trade in the Ottoman Empire that had flourished in the Balkans, the coastal town of Ulcinj in Montenegro had its own black community. As a consequence of the slave trade and privateer activity, it is told how until 1878 in Ulcinj 100 black people lived. The Ottoman Army also deployed an estimated 30,000 Black African troops and cavalrymen to its expedition in Hungary during the Austro-Turkish War of 1716–18.
