The Civil disobedience movement was launched when Gandhi faced humiliation from Lord Irwin. Lord Irwin didn't pay attention to the letter written by Gandhi so he decided to launch a new movement, more intense than non cooperation, in 1930.
The following were the main features of the Civil Disobedience movement:
a) The people refused to obey unjust laws. Gandhi led the Dandi March and broke the unjust salt tax law as a challenge to the British Government.
b) Foreign cloth was boycotted and liquor shops were picketed. Peasants refused to pay revenue and taxes. People also broke the forest laws.
