Abdullah Öcalan, also known as Apo, is a political prisoner and founding member of the militant Kurdistan Workers' Party (PKK).

The Kurdistan Workers' Party or PKK is a Kurdish militant political organization and armed guerrilla movement which historically operated throughout Kurdistan but is now primarily based in the mountainous Kurdish-majority regions of southeastern Turkey and northern Iraq. Since 1984, the PKK has been involved in asymmetric warfare in the Kurdish–Turkish conflict. Although the PKK initially sought an independent Kurdish state, in the 1990s its goals changed to seeking autonomy and increased political and cultural rights for Kurds within Turkey.
