This article examines the role of civil society in the implementation of transitional justice in Turkey’s ongoing Kurdish conflict, which is characterized by historical state violence and a lack of official transitional justice processes. Drawing on 24 interviews, the research reveals the evolution of civil society engagement from its peak during the 2013–2015 peace process to its decline under increasing authoritarianism. The research argues that, despite challenges, civil society retains the potential to drive incremental change in the absence of formal transitional justice mechanisms. However, the authoritarian regime has significantly curtailed its capacity, creating a limited civic space for transitional justice. The article highlights the need for stronger links between civil society in Turkey and international transitional justice scholarship. Such collaboration could empower activists, enabling them to overcome challenges and increase their effectiveness. Turkey offers a unique case for transitional justice scholars and practitioners to learn from civil society actors committed to pursuing justice.
