Quick Summary

The Non-Cooperation Movement was launched by Gandhi in December 1920 due to a combination of immediate triggers and deeper structural factors. The immediate causes included the Khilafat issue (harsh treatment of Turkey affecting Muslim sentiments), the Jallianwala Bagh massacre (killing of hundreds of unarmed civilians in April 1919), the Rowlatt Act (allowing imprisonment without trial), and the Hunter Committee's inadequate response to Punjab atrocities.

Background factors included post-World War I economic distress, failure of the Montagu-Chelmsford reforms to provide meaningful self-governance, and growing nationalist sentiment. Gandhi's strategic thinking involved creating a broad-based alliance uniting Hindus and Muslims, using non-violent methods to exert mass pressure on the British government, and combining moral authority with political action.

The movement was formally launched at the Nagpur Congress session in December 1920, where Gandhi's resolution was passed despite initial opposition from moderate leaders. Key personalities included Gandhi as the leader, the Ali Brothers for Muslim mobilization, and leaders like Motilal Nehru and C.

R. Das who eventually supported the movement. The launch process began with the Calcutta session in September 1920 and culminated in the Nagpur session, marking the beginning of mass participation in the freedom struggle under Gandhi's leadership.
