Operation Blue Star was a military operation by the Indian Armed Forces conducted between 1 and 10 June 1984, with the stated objective of removing Damdami Taksal leader Jarnail Singh Bhindranwale and militants from the buildings of the Golden Temple, the holiest site of Sikhism, in Amritsar. The Shiromani Akali Dal political party and other Sikh factions had been based there during the course of the Dharam Yudh Morcha. The operation would mark the beginning of the Insurgency in Punjab, India.
A long-standing movement advocating for greater political rights for the Sikh community had previously existed in the Indian state of Punjab, and in 1973, Sikh activists presented the Indian government with the Anandpur Sahib Resolution, a list of demands for greater autonomy for Punjab. The resolution was rejected by the Indian government. In July 1982, Harchand Singh Longowal, the president of the Sikh political party Shiromani Akali Dal, invited Bhindranwale to take up residence in the Golden Temple. On 1 June 1984, after abortive negotiations with the Akalis, the Prime Minister of IndiaIndira Gandhi ordered the army to launch Operation Blue Star, attacking the Golden Temple and scores of other Sikh temples and sites across Punjab.
Underestimating the firepower possessed by the Sikh militants, Indian forces unsuccessfully assaulted the Temple using light weaponry but quickly resorted to using heavy arms, including tanks, helicopters and artillery to dislodge the well-fortified Sikh militants. Combat devolved into protracted urban warfare, with the Indian forces committing significant forces to slowly gain ground. Eventually, the Sikh militants ran out of most of their ammunition on 6 June, and by 10 June fighting had largely ceased, with the Indian forces in control of the complex. Many civilians were subject to extrajudicial killings by the military during the operation.
The military action in the temple complex was criticized by Sikhs worldwide, who interpreted it as an assault on the Sikh religion and the entire Sikh community, as well as the root cause for the subsequent insurgency, which would gain further impetus during Operation Woodrose. Five months after the operation, on 31 October 1984, Indira Gandhi was assassinated in an act of revenge by two Sikh bodyguards. Her party, the Indian National Congress, instigated and utilized public sentiment over Gandhi's death, leading to the ensuing 1984 anti-Sikh riots.
Despite accomplishing its stated objectives, the operation has been described as "disastrous" for the Indian military and state. It greatly exacerbated tensions between the Indian government and the Sikh community, turning a series of police operations into widespread sectarian violence. The brutality of the operation and high civilian casualties spawned an insurgency in Punjab, which would be waged by Sikh militants for over a decade. The operation has been used as a case study highlighting the importance of respecting religious and cultural sensitivity prior to launching military operations.
The complex would later be raided twice more as part of Operation Black Thunder I and II, with both operations having little to no civilian casualties or damage to the Temple despite larger amounts of militants than Operation Blue Star.
