The launch of the Non-Cooperation Movement

The Jallianwala Bagh Massacre, Rowlatt Act and Khilafat Movement resulted in unrest among the masses anxious to take political action against the British government. Only added fuel to the fire was the economic hardship suffered by ordinary Indians. On August 1, 1920, the Non - Cooperation Movement was officially launched.
