Denial of Kurds by Turkey

The Republic of Turkey had an official policy in place that denies the existence of the Kurds as a distinct ethnicity. The Kurds, who are a people that speak various dialects of Northwestern Iranic languages, have historically constituted the demographic majority in southeastern Turkey (or "Turkish Kurdistan") and their independent national aspirations have stood at the forefront of the long-running Kurdish–Turkish conflict.
