On the evening of 31 October 1984, while most of Delhi was still absorbing the news that Prime Minister Indira Gandhi had been shot by her Sikh bodyguards, teams of men fanned out through the city's neighborhoods with voter registration lists in hand. They used the lists to identify Sikh homes in mixed, unmarked neighborhoods -- an otherwise impossible task -- and marked each door with the letter "S." By morning, the killing had begun. What followed over the next four days was not a riot in any spontaneous sense. It was an organized massacre, fueled by Congress Party networks, aided by police indifference, and carried out with an unnamed combustible chemical that arson investigators later said required large-scale coordination to procure.
At 9:20 a.m. on 31 October, Indira Gandhi was shot by her Sikh security guards, Satwant Singh and Beant Singh. She died at 10:50 a.m. at the All India Institute of Medical Sciences. By 11 a.m., All India Radio broadcast that the guards were Sikhs. At 5:30 p.m., the motorcade of President Zail Singh -- himself a Sikh -- was stoned as it approached AIIMS; a bodyguard's turban was ripped from his head. That evening, organized gangs began spreading outward from the hospital area. According to investigators, the attacks were planned at the home of the Minister of Information and Broadcasting. Surveyors moved through neighborhoods at night, marking Sikh homes. An elderly Sikh man became the first confirmed fatality around 9 p.m. Rajiv Gandhi was sworn in as prime minister the same night.
The worst killing concentrated in working-class colonies of East Delhi. In Trilokpuri, mobs roamed the narrow alleys beginning on the morning of 1 November. Hundreds of Sikhs were killed over multiple days in what witnesses described as butchery. In one documented account, a father and his two sons were beaten and burned alive. When the mob entered the home, they found the man's wife and youngest son. She was stripped and raped in front of her child. When she tried to flee, the boy was caught, beaten, and burned alive. The woman survived with knife wounds and a broken arm. In the same colony, women were dragged one by one to a mosque to be gang-raped; one girl testified that she was assaulted by fifteen men. Eyewitness reports confirmed the use of a combustible chemical in addition to kerosene. When some Sikhs managed to arm themselves and repel attackers, police arrived -- not to protect them, but to confiscate their weapons and block all exit points, leaving them defenseless.
The Nanavati Commission, established in 2000, found that "local Congress leaders and workers had either incited or helped the mobs in attacking the Sikhs." A Cobrapost sting operation in 2014 revealed that messages were broadcast directing Delhi Police not to act against rioters and that the fire brigade refused to respond to calls from areas where arson was underway. The People's Union for Democratic Rights and the People's Union for Civil Liberties jointly investigated in November 1984, interviewing victims, police, army personnel, and political leaders. Their report, "Who Are the Guilty?," concluded the attacks were "the outcome of a well organised plan marked by acts of both deliberate commissions and omissions by important politicians of the Congress (I) at the top." The Ahuja Committee placed the death toll in Delhi alone at 2,733. A curfew announced on 2 November was not enforced. Army troops deployed through the city were forbidden to fire without consent from senior police officers -- consent that was systematically withheld.
Ten commissions and committees were formed to investigate. The pattern was consistent: investigators recommended charges against Congress leaders; the government delayed, obstructed, or disbanded the committees before action followed. The Marwah Commission was abruptly ordered to halt its police inquiry in 1985. The Kapur Mittal Committee cited 72 police officers for conspiracy or negligence and recommended dismissing 30; none were punished. The Jain Banerjee Committee recommended charges against Sajjan Kumar in 1987, but no case was registered. By 2012, 442 rioters had been convicted in Delhi -- 49 sentenced to life imprisonment. In 2018, the first death sentence was awarded to Yashpal Singh for the murder of Hardev Singh and Avtar Singh in Mahipal Pur, 34 years after the crime. The conviction came only after a Special Investigation Team constituted in 2015 reopened a case that police had closed as "untraced" despite testimony from four eyewitnesses who were the victims' brothers.
In 2010, the Jathedar of the Akal Takht formally declared the events a genocide, replacing the term "anti-Sikh riots" that the Indian government and media had used for decades. California's State Assembly followed in 2015, and Ontario's legislature in 2017. In 2019, Prime Minister Narendra Modi himself called the events a "horrendous genocide." The word matters because "riot" implies spontaneity, and nothing about these four days was spontaneous. Voter lists were used to find the targets. Chemicals were procured in advance. Police were ordered to stand down. The violence catalyzed lasting consequences: many Sikhs felt betrayed by the Indian state, giving momentum to the Khalistan separatist movement. In 2005, Prime Minister Manmohan Singh apologized in Parliament. In 2017, a Wall of Truth was inaugurated in Lutyens' Delhi as a memorial. The Sikh community continues to push for full accountability -- for the commissions shut down, the officers never punished, and the political leaders who orchestrated a massacre and went unprosecuted.
Centered on Delhi, India, at approximately 28.61N, 77.23E, with the worst violence concentrated in East Delhi colonies including Trilokpuri. The Indira Gandhi International Airport (ICAO: VIDP) is the nearest major airport. Violence also occurred across Punjab and in cities including Kanpur and Meerut. From altitude, the dense residential colonies of East Delhi where the worst massacres occurred are indistinguishable from surrounding neighborhoods -- which is precisely why the killers needed voter lists to find their targets. The AIIMS hospital complex (28.57N, 77.21E), where Gandhi died and from which mobs first spread, is visible as a large institutional campus in south-central Delhi.
