In March 1930

Explanation: Civil Disobedience meant refusal by the general public of the country to accept a particular law or rule imposed by the government. This movement was started by Mahatma Gandhi in March 1930 in India, in response to the Salt law imposed by the British government. This law stated that the price of salt would be increased to a thousand times. Gandhiji thought that salt is a basic necessity of life which is required by everyone. This was a nonviolent form of protest centred around Salt.
