The conflict between Turkey and the Kurdistan Workers' Party (PKK) (designated a terrorist organisation by Turkey, the United States, and the European Union) has been active since 1984, primarily in the southeast of the country. More than 40,000 people have died as a result of the conflict. In 1999 PKK's founder Abdullah Öcalan was arrested and sentenced for terrorism and treason charges. In the past, various Kurdish groups have unsuccessfully sought separation from Turkey to create an independent Kurdish state, while others have more recently pursued provincial autonomy and greater political and cultural rights for Kurds in Turkey. In the 21st century some reforms have taken place to improve the cultural rights of ethnic minorities in Turkey, such as the establishment of TRT Kurdî, TRT Arabi and TRT Avaz by the TRT.
