The Non-cooperation movement was launched on 5th September, 1920 by Mahatma Gandhi with the aim of self-governance and obtaining full independence as the Indian National Congress (INC) withdraw its support for British reforms following the Rowlatt Act of 20 March 1919, and the Jallianwala Bagh massacre of 13 April 1919.
Noncooperation movement, unsuccessful attempt in 1920–22, organized by Mohandas (Mahatma) Gandhi, to induce the British government of India to grant self-government, or swaraj, to India. It was one of Gandhi’s first organized acts of large-scale civil disobedience (satyagraha).
