International People's Tribunal on the 1965 Crimes Against Humanity in Indonesia

The International People's Tribunal on the 1965 Crimes Against Humanity in Indonesia (often called IPT 1965) was a civil-society tribunal held in The Hague, Netherlands, from 10 to 13 November 2015 to examine allegations of crimes against humanity committed during the Indonesian mass killings of 1965–66.

The tribunal was organized by Indonesian and international human-rights activists, academics, and survivors in response to what organizers described as the absence of an official domestic process of transitional justice or truth-finding concerning the events of 1965–66. Although the tribunal had no legal authority, it conducted hearings modeled on judicial proceedings and produced a written judgment assessing evidence under international human-rights law.
