Explanation:

JALLIANVALA BAGH MASSACRE, involved the killing of hundreds of unarmed, defenseless Indians by a senior British military officer, took place on 13 April 1919 in the heart of Amritsar, the holiest city of the Sikhs, on a day sacred to them as the birth anniversary of the Khalsa. Jallianvala Bagh, a garden belonging to the Jalla, derives name from that of the owners of this piece of land in Sikh times. It was then the property the family of Sardar Himmat Singh (d.1829), a noble in the court of Maharaja Ranjit Singh (1780-1839), who originally came from the village of Jalla, now in Fatehgarh Sahib district of the Punjab.

The Bagh was acquired by the nation on 1 August 1920 at a cost of 5,60,472 rupees but the actual construction of the memorial had to wait until after Independence. The monument, befittingly named the Flame of Liberty, build at a cost of 9,25,000 rupees, was inaugurated by Dr Rajendra Prasad, the first President of the Republic of India, on 13 April 1961. The central 30-ft high pylon, a four-sided tapering stature of red stone standing in the midst of a shallow tank, is built with 300 slabs with Ashoka Chakra, the national emblem, carved on them.
