Archival Sources on the 1965-1966 Indonesian Mass Killings: Non-Government Perspectives

SUMMARY

The period of 1965-1966 in Indonesia saw widespread violence, often described as a genocide, targeting individuals perceived to support the Indonesian Communist Party (PKI), resulting in an estimated half a million to two million deaths. While government narratives have historically downplayed or omitted these events, a growing body of independent and non-governmental archival efforts seeks to document the experiences of victims and provide counter-narratives. These initiatives include online libraries, oral history projects, and academic studies, many of which aim to expand democratic space and uncover historical truth by collecting testimonies and literature beyond official government statements.

Key efforts include the 1965-1966 Online Genocide Library (POG 1965-1966) established in 2016, and an oral history project launched by the Indonesian Social History Institute (ISSI) in 2003, which interviewed hundreds of victims across various Indonesian islands. These projects utilize annotated bibliographies and survivor testimonies to present a comprehensive digital resource. Despite the Indonesian government holding a public discussion on the violence in 2016, a significant portion of the documentation and archival work on victim perspectives is driven by non-state actors and human rights groups.

STRONGEST CASE FOR

The sheer volume and diversity of independent archival projects, oral history initiatives, and online libraries established by Indonesian academics, activists, and human rights groups demonstrate a concerted effort to document the 1965-1966 events from the perspective of victims and non-state actors. These efforts, such as the POG 1965-1966 and the ISSI oral history project, provide crucial counter-narratives to official government histories, offering a more complete and nuanced understanding of the violence and its impact on Indonesian society through primary testimonies and survivor accounts.

STRONGEST CASE AGAINST

While independent archives and victim testimonies offer valuable perspectives, their methodologies can sometimes face challenges related to memory reliability, potential biases in collection, and limited access to comprehensive state records for cross-verification. Without formal state recognition or access to official government archives, these non-governmental sources may struggle to fully contextualize events or provide irrefutable evidence that can withstand scrutiny from official historical narratives, potentially leaving gaps or areas for dispute.
