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 under the command of Colonel Reginald Dyer. This brutality stunned the entire nation, resulting in a wrenching loss of faith of the general public in the intentions of the UK. The ineffective inquiry and the initial accolades for Dyer by the House of Lords fuelled widespread anger, leading to the Non-cooperation Movement of 1920–22.
