The Non-Cooperation Movement was pitched in under leadership of Mahatma Gandhi and the Indian National Congress from September 1920 to February 1922, marking a new awakening in the Indian Independence Movement. After a series of events including the Jallianwala Bagh Massacre, Gandhiji realised that there was no prospect of getting any fair treatment at the hands of British, so he planned to withdraw the nation's co-operation from the British Government, thus launching the Non-Cooperation Movement and thereby marring the administrative set up of the country. This movement was a great success as it got massive encouragement to millions of Indians. This movement almost shook the British authorities.
