title: Non-cooperation movement
text: The Non-Cooperation Movement was a significant phase of the Indian independence movement from British rule . It was led by Mohandas Karamchand Gandhi after the Jallianwala Bagh Massacre . It aimed to resist British rule in India through non-violent means , or `` Ahinsa '' . Protesters would refuse to buy British goods , adopt the use of local handcrafts and picket liquor shops . The ideas of Ahinsa and nonviolence , and Gandhi 's ability to rally hundreds of thousands of common citizens towards the cause of Indian independence , were first seen on a large scale in this movement through the summer of 1920 . Gandhi feared that the movement might lead to popular violence . The non-cooperation movement was launched on 1 August 1920 .
