Caucasian refugees (1860s–1910s) When refugees from
Caucasus reached the
Ottoman Empire, Constantinople decided not to settle these in Kurdistan due to the
extreme poverty and lack of material resources for the refugees. Yet after some time, the Ottomans started seeing the refugees as a chance to diminish the Kurdish claim to the region and allowed the refugees to settle in the region. In 1862,
Circassian refugees from the
Shapsug tribe arrived in the Kurdish areas of
Ahlat and
Adilcevaz and settled in the three Kurdish villages of Yoğurtyemez, Xanik (Çukurtarla), Develik and founded the village of Koxiş (Yolçatı). The first big wave of Caucasian refugees to Kurdistan was in 1864 when 15,000 to 20,000 refugees settled in
Sarıkamış, founding new villages and settling in abandoned Greek and Armenian villages. The largest group of refugees were Circassias who fled the
Circassia region (part of the
Russian Empire) during the
ethnic cleansing of Circassians. Concurrently with the Circassian migration,
Ossetians settled in the villages of Xulik (Otluyazı) and Ağcaviran (Akçaören) in Ahlat. According to the Russian intelligence officer Aleksandr Kolyubakin, no less than 1,500 Ossetians lived in the
Sanjak of Muş in the late 1880s. From early stage on, these Caucasians went through a process of Kurdification and thereby had Kurdish as their mother tongue.
Urbanization of Kurds With the departure of non-Muslim populations of many cities in regions with significant Kurdish population, the native urban Muslim populations also migrated to cities such as
Gaziantep,
İzmir,
Adana,
Ankara, and
Istanbul. The tractorization in rural Kurdish communities during the 1950s and the later abandonment of villages due to the
Kurdish-Turkish conflict caused many Kurds to migrate to nearby cities that were losing their native population such as
Diyarbakır but also to distant cities like
Mersin, either mostly or partially Kurdifying the ethnic makeup. The aim of the resettlements and depopulation of the Kurdish population from villages to the cities were the
Turkification of the Kurdish population or according to
İsmail Beşikçi the destruction of the Kurdish nation. ==Iraq==
