Timeline of the Kurdistan Workers' Party insurgency (1978–2015)

This is the timeline of the Turkish-Kurdish conflict. The Kurdish insurgency is an armed conflict between the Republic of Turkey and various Kurdish insurgent groups, which have demanded separation from Turkey to create an independent Kurdistan, or to have autonomy and greater political and cultural rights for Kurds in Turkey. The main rebel group is the Kurdistan Workers' Party or PKK, which was founded on November 27, 1978, and started a full-scale insurgency on August 15, 1984, when it declared a Kurdish uprising. Apart from some extended ceasefires (most recently during the 2013-2015 Kurdish-Turkish peace process), the conflict has continued to the present day.
