Operation Blue Star, a military offensive, is launched by the Indian government at Harmandir Sahib, also known as the Golden Temple, the holiest shrine for Sikhs, in Amritsar. The operation continues until June 6, with casualties, most of them civilians, in excess of 5,000.

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. The 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.

The Golden Temple is a gurdwara located in Amritsar, Punjab, India. It is the pre-eminent spiritual site of Sikhism. It is one of the holiest sites in Sikhism, alongside the Gurdwara Darbar Sahib Kartarpur in Kartarpur, and Gurdwara Janam Asthan in Nankana Sahib.

Sikhs are an ethnoreligious group and nation who adhere to Sikhism, a religion that originated in the late 15th century in the Punjab region of the Indian subcontinent, based on the revelation of Guru Nanak. The term Sikh has its origin in the Sanskrit word śiṣya, meaning 'seeker', 'disciple' or 'student'.
