The Kurdistan Workers' Party or PKK (Kurdish: Partiya Karkerên Kurdistanê) is a left-wing organization based in Turkey and Iraq. Since 1984 the PKK has been involved in an armed conflict with the Turkish state, with the initial aim of achieving an independent Kurdish state, which has since shifted to a demand for equal rights, freedom, and a more democratic Turkey.
The group was founded in 1978 in the village of Fis (near Lice) by a group of Kurdish students led by Abdullah Öcalan. The PKK's ideology was originally a fusion of revolutionary socialism and Kurdish nationalism, seeking the foundation of an independent, Marxist–Leninist state in the region, which was to be known as Kurdistan. The initial reason given by the PKK for this was the oppression of Kurds in Turkey.
Since PKK leader Öcalan's capture and imprisonment in 1999, he has moved on from Marxism–Leninism, leading the party to adopt his new political platform of Democratic Confederalism while ceasing its official calls for the establishment of a fully independent country. In May 2007, former members of the PKK helped form the Kurdistan Communities Union (KCK), an umbrella organisation of Kurds from Turkey, Iran, Iraq, and Syria.
In 2013, the PKK declared a ceasefire agreement and began slowly withdrawing its fighters to the Kurdistan Region of northern Iraq as part of the "solution process" between the Turkish state and the long-disenfranchised Kurdish minority. In July 2015, the PKK announced that a ceasefire was over and said that Ankara had welched on its promises regarding the Kurdish issue. In August 2015, the PKK announced that they would accept a ceasefire with Turkey under United Nations or US guarantees.
The PKK is listed as a terrorist organization by several states and organizations, including the North Atlantic Treaty Organization (NATO), the United States and the European Union. However, the United Nations and countries such as Switzerland, China, India, Russia and Egypt have not designated the PKK as a terrorist organization.
