• A brief survey of the nature of Civil Disobedience Movement in different parts of the subcontinent is given below: ? Tamil Nadu: In April 1930, C. Rajagopalachari organised a march from Thiruchirapalli to Vedaranniyam on the Tanjore coast to break the salt law.
• Malabar: K. Kelappan, a Nair Congress leader famed for the Vaikom Satyagraha, organised salt marches. ? Orissa: Under Gopalbandhu Chaudhuri, a Gandhian leader, salt satyagraha proved effective in the coastal regions of Balasore, Cuttack and Puri districts. ? Bihar: The tribal belt of Chhotanagpur (now in Jharkhand), saw instances of lower-class militancy.
• Bonga Majhi and Somra Majhi, influenced by Gandhism, led a movement in Hazaribagh which combined socio-religious reform along =sanskritising‘ lines, in which followers were asked to give up meat and liquor, and use khadi. ? Dharasana: In May 1930, Sarojini Naidu, Imam Sahib and Manilal (Gandhi‘s son) took up the unfinished task of leading a raid on the Dharasana Salt Works.
