Russia, which had been defeated by the Crimean War, began to carry out policies of oppression, violence and assimilation against the people of the region on the grounds that the people of the Caucasus did not give them the necessary support. As a result of these policies implemented by Russia, the people of the region have to migrate to the territories of the Ottoman State which have historical, religious and economic ties. The immigration movement that began with the voluntary arrival of some Caucasian families in the first half of the 1850s on the territory of the Ottoman State began to gain intensity from 1859. But the migrations which have been declining slightly began to intensify again after the Ottoman-Russian War of 1877-1878. However, after the Ottaman-Russian War of 1877-1878, the migration movement also increased again. This immigration movement, which increased and decreased during various periods, continued until the first years of the 20th century.
