A violent incident occurred in India on April 13, 1919. It involved a British military commander ordering his forces to open fire on peaceful protesters. This incident sparked an international outrage. The incident was called the Amritsar Massacre.
The Amritsar massacre was a massacre in the city of Amritsar on April 13, 1919, when soldiers of the British Indian Army commanded by General Reginald Dyer machine-gunned a crowd of thousands of unarmed Sikhs, Hindus and Muslims people, who were gathered in the Jallianwala garden for the Vaisakhi festival.
The massacre permanently marked the relations between India and the United Kingdom of Great Britain and Ireland, being historically the prelude to the non-cooperation movement led by Mahatma Gandhi between 1920 and 1922.
