The Peoples' Democratic Party (Turkish: Halkların Demokratik Partisi, acronymized as HDP; Kurdish: Partiya Demokratîk a Gelan), or Democratic Party of the Peoples, is a Turkish political party mainly representing ethnic minorities in Turkey, especially Kurds. Generally left-wing, the party places a strong emphasis on participatory and radical democracy, feminism, minority rights, youth rights, and egalitarianism. It is an associate member of the Party of European Socialists (PES), a consultative member of the Socialist International, and a party within the Progressive Alliance (PA).
Aspiring to fundamentally challenge the existing Turkish–Kurdish divide and other existing parameters in Turkish politics, the HDP was founded in 2012 as the political wing of the Peoples' Democratic Congress, a union of numerous left-wing movements that had previously fielded candidates as independents to bypass the 10% election threshold. The HDP is in an alliance with the Kurdish Democratic Regions Party (DBP), often described as the HDP's fraternal party. From 2013 to 2015, the politicians of the DBP participated in peace negotiations between the Turkish government and the Kurdistan Workers' Party (PKK).
