The aims of this research were (1) to explain the historiography development of the 1965 G30S, (2) to elaborate the relation among ideology, domination, and the nation hegemony in the history writing development of 1965 G30S, and (3) to reconstruct and to deconstruct the 1965 G30S historiography using the millennial historiography perspective. This research employed the critical history method which steps consisted of heuristics (source collecting), source criticisms (internal and external criticisms), interpretations (analysis and synthesis), and the historiography (the writing of the research result). As the approach, this research focused on the Discourse-Historical Approach (DHA). This research showed several findings (1) The 1965 G30S historiography development was traceable through the development of the Indonesian national history seminar from 1957 up to the post 1998 reformation. The background of 1965 G30S history writing was the quarrel for the definition and the mastermind or the actor of that incident. (2) The 1965 G30S historiography became the bond among ideology, domination, and the nation hegemony of the New Order. The 1965 G30S historiography not only became the basic of the power legitimation but also the dichotomy foundation between “the friends” and “the enemies” in the economic, politic, and social lives in Indonesia under the New Order regime (oligarch). As the impact, the history writing could only be done by “the nation”. The society who were critical through the new order interpretation would be considered as a threat for the nation stability. (3) The fall of the New Order in 1998 brought the opportunity for the Indonesia history writing, including the historiography reconstruction and deconstruction of the 1965 G30S using the millennial perspective. The millennial historiography rejected the “official” theory of the G30S/PKI, and at once revealed the G30S/AD theory, G30S/Sukarno theory, G30S/CIA theory, G30S/Suharto theory, G30S/Chaos theory, and the G30S/Sjam theory.
Key word: Millennial Historiography, G30S, New Order, Reformation.
