In the middle of the 19th century, a huge amount of emigrants from the Balkan countries, Crimea and the Caucasus had emigrated to the Ottoman state. Most of the Caucasian emigrants who belonged to Abkhaz, Adige (Circassian), Karachay-Balkar, Osset, Chechen-Ingush and Dagestan peoples had come to the Ottoman state between 1858-1864 years. The Emigrant Comission of the Ottoman state was in trouble to settle the emigrants in the proper lands of the state, because the Caucasian emigrants had different languages, customs and social structures. The social strafication system and the slavery institution of the Caucasian emigrants had caused problems in the settlement policy of the Ottoman state. In the Ottoman archives there are a lot of documents about the slavery institution and the social strafication system of the Caucasian emigrants
