Document 7: Suharto: General of the Army Hajji Suharto (also spelled Soeharto;    , or Muhammad Soeharto; Javanese : ꦩꦸꦲꦩ꧀ꦩꦢ꧀ꦯꦸꦲꦂꦠ ; 8 June 1921 – 27 January 2008) was the second President of Indonesia, holding the office for 31 years from the ousting of Sukarno in 1967 until his resignation in 1998.
Document 8: New Order (Indonesia): Immediately following the attempted coup in 1965, the political situation was uncertain, but the Suharto's New Order found much popular support from groups wanting a separation from Indonesia's problems since its independence. The 'generation of 66' ("Angkatan 66") epitomised talk of a new group of young leaders and new intellectual thought. Following Indonesia's communal and political conflicts, and its economic collapse and social breakdown of the late 1950s through to the mid-1960s, the "New Order" was committed to achieving and maintaining political order, economic development, and the removal of mass participation in the political process. The features of the "New Order" established from the late 1960s were thus a strong political role for the military, the bureaucratisation and corporatisation of political and societal organisations, and selective but effective repression of opponents. Strident anti-communism remained a hallmark of the regime for its subsequent 32 years.

Document 12: Indonesian mass killings of 1965–1966: The Indonesian mass killings of 1965–1966 (also variously known as the Indonesian massacres, Indonesian genocide, Indonesian Communist Purge, Indonesian politicide, or the 1965 Tragedy) were large-scale killings and civil unrest which occurred in Indonesia over many months, targeting communist sympathizers, ethnic Chinese and alleged leftists, often at the instigation of the armed forces and government. Initially it began as an anti-communist purge following a controversial coup attempt by the 30 September Movement in Indonesia. The most widely published estimates were that 500,000 to more than one million people were killed, with some more recent estimates going as high as two to three million. The purge was a pivotal event in the transition to the "New Order" and the elimination of the Indonesian Communist Party (PKI) as a political force. The upheavals led to the fall of President Sukarno and the commencement of Suharto's three-decade authoritarian presidency.
Document 13: May 1998 riots of Indonesia: The May 1998 riots of Indonesia (Indonesian: "Kerusuhan Mei 1998" ), also known as the 1998 Tragedy (Indonesian: "Tragedi 1998" ) or simply the 1998 event (Indonesian: "Peristiwa 1998" ) were incidents of mass violence, demonstrations, and civil unrest of a racial nature that occurred throughout Indonesia, mainly in Medan in the province of North Sumatra (4–8 May), the capital city of Jakarta (12–15 May), and Surakarta (also called Solo) in the province of Central Java (13–15 May). The riots were triggered by economic problems including food shortages and mass unemployment, and eventually led to the resignation of President Suharto and the fall of the New Order government. The main targets of the violence were Chinese ethnic, however, most of the people who died in the riots were the Javanese Indonesian looters who targeted the Chinese shops, not the Chinese themselves, since the looters were burnt to death in a massive fire.
Document 14: List of accolades received by The Act of Killing: "The Act of Killing" (Indonesian: "Jagal" ) is a 2012 Danish-British-Norwegian documentary film directed by Joshua Oppenheimer, Christine Cynn, and an anonymous Indonesian co-director. The film explores the social significance of the Indonesian mass killings of 1965–1966 by focusing on the perpetrators and having them produce reenactments of the killings in the style of various Hollywood genres. The film's primary subjects had been petty criminals, but came to lead a powerful death squad during the anti-communist purge which resulted in the death of an estimated 500,000–2,000,000 suspected communists, communist sympathisers, alleged leftists, and ethnic Chinese. As many of the institutions and people responsible remained in power, those who carried out the killings were never held to account and continue to hold positions of power and respect. Oppenheimer was struck by the extent to which people not only rationalised but boasted about their participation in the killings, and used the film to explore the role the events continue to play in people's lives in the present. According to Oppenheimer, it is "about a regime in which genocide has, paradoxically, been effaced and celebrated – in order to keep the survivors terrified, the public brainwashed, and the perpetrators able to live with themselves."
Document 15: 1997–98 activists kidnappings in Indonesia: The 1997/1998 activists kidnapping were abductions of pro-democracy activists which happened between the 1997 Indonesian Legislative Election and the fall of Suharto in 1998. The kidnappings took place in three different phases: before the May 1997 Indonesian legislative elections, two months before the People's Consultative Assembly (MPR) session in March 1998 and in the period just before Soeharto's 21 May resignation. None of those abducted during the first and third period have reappeared. Some of the activists who were abducted in the second period have openly spoken about their experiences.
