Jallianwala Bagh Massacre, also called Massacre of Amritsar, incident on April 13, 1919, in which British troops fired on a large crowd of unarmed Indians in an open space known as the Jallianwala Bagh in Amritsar in the Punjab region (now in Punjab state) of India, killing several hundred people and wounding many hundreds more. It marked a turning point in India’s modern history, in that it left a permanent scar on Indo-British relations and was the prelude to (Mahatma) Gandhi’s full commitment to the cause of Indian nationalism and independence from Britain.

The acts were met by widespread anger and discontent among Indians, notably in the Punjab region. Gandhi in early April called for a one-day general strike throughout the country. In Amritsar the news that prominent Indian leaders had been arrested and banished from that city sparked violent protests on April 10, in which soldiers fired upon civilians, buildings were looted and burned, and angry mobs killed several foreign nationals and severely beat a Christian missionary. A force of several dozen troops commanded by Brig. Gen. Reginald Edward Harry Dyer was given the task of restoring order. Among the measures taken was a ban on public gatherings.

Rowlatt Acts, (February 1919), legislation passed by the Imperial Legislative Council, the legislature of British India. The acts allowed certain political cases to be tried without juries and permitted internment of suspects without trial. Their object was to replace the repressive provisions of the wartime Defence of India Act (1915) by a permanent law. They were based on the report of Justice S.A.T. Rowlatt’s committee of 1918.
