When the Rowlatt Acts were passed, 10,000 Hindus and Muslims went to Amritsar to protest by fasting and praying. Later on, a British Commander thought that these protestors were breaking the Rowlatt Acts. So, he ordered his soldiers to fire at the protesters. Approximately 400 Indian people died and nearly 1,200 were injured by the soldiers. This event was later on known as the Amritsar Massacre.
