The Rowlatt Act, officially known as the Anarchical and Revolutionary Crimes Act of 1919, was a legislative measure passed by the British government in India. The primary aim of this act was to curb the rising nationalist sentiment in the country by implementing stringent measures.

One of the key features of this act was that it authorized the government to imprison any person suspected of terrorist activities without a trial. This provision allowed for indefinite detention and imprisonment without any need for a trial or conviction in a court of law.

Therefore, the Rowlatt Act primarily aimed at imprisonment without trial and summary procedures for trial.
