The Kurds are the largest ethnic minority in Turkey. According to various estimates, they compose between 15% and 20% of the population of Turkey. There are Kurds living in various provinces of Turkey, but they are primarily concentrated in the east and southeast of the country, within the region viewed by Kurds as Turkish Kurdistan. Officially in Eastern Anatolia and Southeastern Anatolia Regions. Massacres, such as the brutal suppression of the Sheikh Said Rebellion, the Dersim ethnocide, and the Zilan massacre, have periodically been committed against the Kurds since the establishment of the Republic of Turkey in 1923. The Turkish government categorized Kurds as "Mountain Turks" until 1991, and denied the existence of Kurds. The words "Kurds" or "Kurdistan" were banned in any language by the Turkish government, though "Kurdish" was allowed in census reports. Following the military coup of 1980, the Kurdish languages were officially prohibited in public and private life. Many people who spoke, published, or sang in Kurdish were arrested and imprisoned.

Since the 1980s, Kurdish movements have included both peaceful political activities for basic civil rights for Kurds in Turkey as well as armed rebellion and guerrilla warfare, including military attacks aimed mainly at Turkish military bases, demanding first a separate Kurdish state and later self-determination for the Kurds. According to a state-sponsored Turkish opinion poll, 59% of self-identified Kurds in Turkey think that Kurds in Turkey do not seek a separate state (while 71.3% of self-identified Turks think they do). During the Kurdish–Turkish conflict, food embargoes were placed on Kurdish villages and towns. There were many instances of Kurds being forcibly expelled from their villages by Turkish security forces. Many villages were reportedly set on fire or destroyed. Throughout the 1990s and early 2000s, political parties that represented Kurdish interests were banned. In 2013, a ceasefire effectively ended the violence until June 2015, when hostilities renewed between the PKK and the Turkish government over Turkish involvement in the Syrian Civil War.
