Ottomans have completed the conquest of Bosnia and Herzegovina in the second half of 15th century. Islam has started to spread among Bosnians with the very beginning of this conquest. After that, Bosnians have accepted the Ottoman-Turk culture and considered the Ottoman lands as their motherland.Even though the Serbian revolt against Ottoman Empire, which started with their alliance with Montenegrins, was suppressed in the late October 1876 with defiance of Serbians, Montenegrins continued the revolt alone in the mountainous terrains of Montenegro. When the Ottoman-Russian war started in 1877 the Montenegrin revolt was stil on. Bosnian immigration to the other Ottoman territories has started in 1878 due to the capture of Niksic –a Bosnian city- by Montenegrin troops supported by Russia, and the Berlin Treaty. Bosnian immigration to Turkey continued later on due to Ottoman-Russia and Ottoman-Austria wars, and the inner conflicts. During the Turkish Republic period this immigration has continued by population exchanges. And lately, another immigration wave has happened during the Bosnia War, but most of these immigrants have returned their home after the peace treaty.Bosnian immigrants have reached firstly to the Ottoman territories in Balkans, and then reached out to Istanbul later on. Ottoman government settled down Bosnian immigrants starting with Istanbul and surrounding regions. These settlements include several regions such as İstanbul, Edirne, İzmit, Sakarya, Bursa, Eskişehir, Manisa, İzmir, Ankara, Amasya, Sivas, Erzincan, Samsun, Trabzon, and Adana. Bosnian immigrants were settled down to cities, towns and villages based on their professions.Immigrants’ expenses such as travel, housing, food, settlement, and building up a business were covered by Immigrant Settlement Commission (Muhacirin İskan Komisyonu), established by the government. Immigrants’ house construction expenses either in cities or villages were covered mostly by the state. Also state helped those settled down in cities to establish a business and those settled down in villages by supplying them with stocks, seeds and farming land.Bosnian immigrants have important economical and cultural impact on Turkish society. Some rich immigrants have established good business and contribute a lot to Turkish trade and production.

Also they contribute to cultural richness in Turkey with their traditions and culture.There is much important information on Ottoman, Turkish Republic, and British archives on this issue.
