Kurdification
Kurdification is a cultural change in which people, territory, and language become Kurdified, i.e. become Kurdish. This can happen both naturally (as in Turkish Kurdistan) or as a deliberate government policy (as in Iraq after the 2003 invasion). The notion of Kurdification is different from country to country. In Turkish Kurdistan, many ethnic Armenians, Bulgarians, Circassians, Chechens, Georgians, Ingushs, and Ossetians have become Kurdified as a result of fleeing to the region and having subsequently assimilated with Kurds. In Iraqi Kurdistan, territories belonging to minorities such as Turkmens and Assyrians were subjected to Kurdification policies until 2017 in the  disputed territories of northern Iraq, when the Kurdistan Regional Government administered the area. More recently during the Syrian Civil War, the Syrian Democratic Forces have been accused of Kurdifying traditional Arab lands. Turkey. 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. These refugees included Circassians, Chechens, Laks and Avars. The largest group of refugees were Circassias who fled the Circassia region (part of the Russian Empire) during the ethnic cleansing of Circassians. Two years later, Shapsug tribe with members  of the Abzakh tribe founded the villages of Bolethan (Karapolat), Arnis (Güzgülü) and Ximsor (Eskibalta) near Bingöl. Concurrently with the Circassian migration, Ossetians settled in the villages of Xulik (Otluyazı) and Ağcaviran (Akçaören) in Ahlat, Yaramış, Karaağıl, Hamzaşeyx (Sarıpınar), Simo (Kurganlı) in the eastern Muş region, and Lekbudak (Budaklı) near Karaçoban. According to the Russian intelligence officer Aleksandr Kolyubakin, no less than 1,500 Ossetians lived in the Sanjak of Muş in the late 1880s. Chechens and Ingushs mostly settled in Varto area, in the villages of Arincik (Kıyıbaşı), Çarbuhur (Bağiçi), Tepeköy, Artet (Serinova), Ulusırt and Arinç (Çöğürlü), Avars who settled  in Kayalık village, and Circassians of the Kabardian tribe founded the village of Narlı Çerkezleri (Eskinarlı) in Pazarcık area. There is also a Georgian village in Diyarbakir Province. From early stage on, these Caucasians went through a process of kurdification and thereby had Kurdish as their mother tongue. 20th–21st century and PKK. When the Kurdish question rose in Turkey, it also had an effect on their Caucasian neighbours. Even today, there is an aversion from joining the Kurds in their conflict against the Turkish state, but some individuals of Caucasian origin joined the Kurdistan Workers' Party. As part of their  campaign, the Kurdish party Peoples' Democratic Party won most Caucasian villages in Turkish Kurdistan. Iraq. Shabaks. On 21 August 2006, Shabak Democratic Party leader Hunain Qaddo, proposed the creation of a separate province within the borders of the Nineveh Plain, arguing that the move was to combat the Arabization and Kurdification of Iraqi minorities. The Iraqi government voted against the proposition. After 2011. Some Assyrians in the Kurdistan Region of Iraq complained that construction plans are "aimed at affecting a demographic change that divides Assyrian blocs". Also some Yazidis, Shabaks and Turkmens have reported that they are facing a policy  of cultural and security control against them. In 2016, David Romano, Professor of Middle East Politics, said that without the YPG and Peshmerga, the Assyrians of northern Syria and Iraq would likely all be dead, lying in some jihadist-dug mass grave. During the Iraqi Civil War, Iraqi army troops fled their posts around the Nineveh Plains while ISIL attacked. Later, KRG forces, with the support of coalition airstrikes, captured these areas from ISIL. Since then, there have been disputes between pro-government Assyrians and Kurds, as the former have either asked the Kurds to leave or promised them autonomy . In 2011, some Yazidi activists voiced their "concern over forced assimilation into Kurdish identity". Some have accused the Kurdish and Iraqi parties of diverting US $12 million of reconstruction funds allocated for Yazidi areas in Jebel Sinjar to a Kurdish village and marginalizing them politically. According to Sweden-based economist David Ghanim, the goal of some tactics of the KRG had been to push Shabak and Yazidi communities to identify as Kurds, which has been strongly denied by KRG authorities. He also claimed that the Kurdish authorities are working to impose Kurdish identity on the Yazidis and the Shabaks . The Kurdish regional government has also been accused of trying to Kurdify other regions such as the Nineveh Plains and Kirkuk by providing financial support for Kurds who want to settle in those areas. Kirkuk. While Kurdish forces held the city of Kirkuk, Kurdish authorities attempted to Kurdify the city. Turkmen and Arab residents in Kirkuk experienced intimidation, harassment and were forced to leave their homes, in order to increase the Kurdish demographic in Kirkuk and bolster their claims to the city. Multiple Human Rights Watch reports detail the confiscation of Turkmen and Arab families' documents, preventing them from voting , buying property and travelling. Turkmen residents of Kirkuk were detained by Kurdish forces and compelled to leave the city. Kurdish authorities expelled hundreds of Arab families from the city, demolishing their homes in the process. United Nations reports since 2006 have documented that Kurdish authorities and Peshmerga militia forces were illegally policing Kirkuk and other disputed areas, and that these militia have abducted Turkmen and Arabs, subjecting them to torture. Iran. Küresunni Turks. In the southwest of Khoy, there are Kurdicized groups of Küresünni Turks. Syria. During the Syrian Civil War, the Syrian Democratic Forces, have been accused of Kurdification .
