What happened in British India in the year 1919?

In 1919, British India experienced significant unrest due to widespread discontent over colonial rule and the repressive Rowlatt Act, which allowed for the detention of Indians without trial. This led to the Jallianwala Bagh massacre on April 13, where British troops killed hundreds of unarmed Indian civilians gathered for a peaceful protest in Amritsar. The incident galvanized Indian nationalist sentiments and intensified calls for independence from British rule, marking a pivotal moment in the struggle for India's freedom.
