Kurdification is a cultural change in which people, territory, or language become Kurdish. This can happen both naturally (as in Turkish Kurdistan) or as a deliberate government policy (as in Iraq after the 2003 invasion or in Syria after Syrian civil war). 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 to the Kurdish culture and language.
