1984 anti-Sikh riots

The 1984 anti-Sikh riots, also known as the 1984 Sikh massacre, was a series of organised pogroms against Sikhs in India following the assassination of Indira Gandhi by her Sikh bodyguards. Government estimates project that about 2,800 Sikhs were killed in Delhi and 3,350 nationwide, whilst other sources estimate the number of deaths at about 8,000–17,000.

The assassination of Indira Gandhi itself had taken place after she had ordered Operation Blue Star, a military action to secure the Harmandir Sahib Sikh temple complex in Amritsar, Punjab, in June 1984. The operation had resulted in a deadly battle with armed Sikh groups who were demanding greater rights and autonomy for Punjab and the deaths of many pilgrims. Sikhs worldwide had criticized the army action and many saw it as an assault on their religion and identity.

In the aftermath of the pogroms, the government reported that 20,000 had fled the city; the People's Union for Civil Liberties reported "at least" 1,000 displaced persons. The most-affected regions were the Sikh neighborhoods of Delhi. Human rights organizations and newspapers across India believed that the massacre was organized. The collusion of political officials connected to the Indian National Congress in the violence and judicial failure to penalize the perpetrators alienated Sikhs and increased support for the Khalistan movement. The Akal Takht, Sikhism's governing body, considers the killings a genocide.

In 2011, Human Rights Watch reported that the Government of India had "yet to prosecute those responsible for the mass killings". According to the 2011 WikiLeaks cable leaks, the United States was convinced of the Indian National Congress' complicity in the riots and called it "opportunism" and "hatred" by the Congress government, of Sikhs. Although the U.S. has not identified the riots as genocide, it acknowledged that "grave human rights violations" occurred. In 2011, the burned sites of multiple Sikh killings from 1984, were discovered in Hondh-Chillar and Pataudi areas of Haryana. The Central Bureau of Investigation, the main Indian investigative agency, believes that the violence was organised with support from the Delhi police and some central-government officials.

After 34 years of delay, in December 2018, the first high-profile conviction for the 1984 anti-Sikh riots took place with the arrest of Congress leader Sajjan Kumar, who was sentenced to life imprisonment by the Delhi High Court. Very few convictions have taken place in the pending 1984 cases, with only one death penalty conviction for an accused, Yashpal in the case of murdering Sikhs in the Mahipalpur area of Delhi.
