Non Cooperation Movement 1922
It was the first of all nonviolent protests in India. Noncooperation movement officially started the Gandhian era in India. The sole aim behind this movement was to make people of India aware of that the British government can be opposed. During the protest, people refused to buy British goods and adopt the use of local handicrafts. Initially, the protest was going well and encouraged millions of Indians to stand up for the freedom. But, Chauri Chaura clash between police and the protesters ended up the dream of Gandhi Ji. He called off mass noncooperative movement and went on fast to stop the massacre.
