When did the Jallianwala Bagh massacre take place?

The Jallianwala Bagh massacre, also known as the Amritsar massacre, took place on 13 April 1919, when a crowd of nonviolent protesters, along with Baishakhi pilgrims, who had gathered in Jallianwala Bagh, Amritsar, Punjab, were fired upon by troops of the British Indian Army. The civilians, in the majority Sikhs, had assembled to participate in the annual Baisakhi celebrations, a religious and cultural festival for Punjabi people and also to condemn the arrest and deportation of two national leaders, Satya Pal and Dr Saifuddin Kitchlew. Coming from outside the city, they may have been unaware of the imposition of martial law.

The Jallianwala Bagh is a public garden of 6 to 7 acres walled on all sides with five entrances. To enter, troops first blocked the entry by a tank and locked the exit. On Dyer's orders, his troops fired on the crowd for ten minutes, directing their bullets largely towards the few open gates through which people were trying to flee. The British government released figures stating 379 dead and 1,200 wounded.

A memorial, designed by American architect Benjamin Polk, was built on the site and inaugurated by President of India Rajendra Prasad on 13 April 1961. A flame was later added to the site. The bullet marks remain on the walls and adjoining buildings to this day. The well into which many people jumped and drowned attempting to save themselves from the bullets is also a protected monument inside the park.
