The Amritsar Massacre happened on April 13, 1919 when British troops fired on unarmed Indians in Jallianwala Bagh in Amritsar. Following the end of WWI, the Indian government passed the Rowlatt Acts which led to protests and discontent. On April 10, the British military fired on a violent protest and increased measures to calm the unrest such as banning public meetings. Then on April 13, soldiers fired on a peaceful open meeting, killing an estimated 380 people, including children, and wounding over 1,200. Following the massacre, the region was put under martial law.
