In pictures: Forty years of Delhi’s anti-Sikh riots

On the morning of 31 October 1984, India’s prime minister Indira Gandhi was assassinated by her bodyguards as she stepped out of her official residence in capital Delhi.

The daughter of India’s Independence leader and first prime minister, Jawaharlal Nehru, she was serving her fourth term in the highest office.

A day before her assassination, Gandhi told a political rally in the eastern state of Odisha (formerly Orissa), “I don’t mind if my life goes in the service of the nation. If I die today, every drop of my blood will invigorate the nation.”

Often termed as the “Iron Lady”, Gandhi played a significant role in India’s eastern neighbour Bangladesh winning independence from Pakistan in 1971.

In 1975, she imposed a state of emergency for a 21-month period from June 1975 to March 1977. The period was marked by massive media censorship, restrictions on civil rights and a forced mass sterilisation campaign.

Gandhi lost the next parliamentary election, including her own seat, but returned with a decisive mandate within months.

In the 1980s, Sikh separatists in Punjab demanded an independent homeland, called Khalistan. In 1984, Gandhi ordered a massive military action against those who were sheltering in Amritsar’s Golden Temple, the faith’s holiest shrine.

About 400 people, including soldiers and pilgrims, were killed during the military raid known as Operation Blue Star. Sikh groups dispute this figure, claiming thousands died.

Within months, Gandhi was assassinated by her Sikh bodyguards, allegedly seeking revenge for her decision to send troops inside the shrine.

The news of her death sparked violent attacks on Sikhs by her supporters in Delhi and beyond, with nearly 3,000 killed within days.

Forty years on, victims continue to seek justice, as many accused remain acquitted and appeals are still pending in court.
