Operation Blue Star (1 – 6 June 1984) was an Indian military operation ordered by Indira Gandhi, the Prime Minister of India to curb and remove Sikh militants from the Golden Temple in Amritsar.
The operation was carried out by Indian army troops with tanks and armoured vehicles.
Militarily successful, the operation aroused immense controversy, and the government's justification for the timing and style of the attack are hotly debated.
Operation Blue Star was included in the Top 10 Political Disgraces by India Today magazine.

Official reports put the number of deaths among the Indian army at 83, with 493 civilians and Sikh militants killed.
In addition, the CBI is considered responsible for seizing historical artefacts and manuscripts in the Sikh Reference Library before burning it down.
Four months after the operation, on 31 October 1984, Indira Gandhi was assassinated by two of her Sikh bodyguards in what is viewed as an act of vengeance.
Following her assassination, more than 3,000 Sikhs were killed in anti-Sikh pogroms.
