On 10 April 1919, there was a protest at the residence of the Deputy Commissioner of Amritsar, a city in Punjab, a large province in the northwestern part of India.
The demonstration was to demand the release of two popular leaders of the Indian Independence Movement, Satya Pal and Saifuddin Kitchloo, who had been earlier arrested by the government and moved to a secret location.
Both were proponents of the Satyagraha movement led by Mohandas Karamchand Gandhi.
The peaceful gathering was attended by men, women and children.
General Dyer, a British military officer, declared the meeting illegal and without warning ordered his soldiers to fire.
The firing lasted for ten minutes, till all the ammunition was exhausted.
More than a thousand people were killed and over twice that number wounded.
The massacre inflamed the anger of the Indians.
There were widespread protests. Rabindranath Tagore renounced his knighthood I protest.
