C. R. Das

Das successfully defended Aurobindo Ghosh in the Alipore Bomb Case, securing his acquittal. The case involved charges of sedition and conspiracy against the British government, and Das's legal skills earned him national fame.

Das became the president of the Bengal Provincial Congress Committee and led the non-cooperation movement in Bengal. He organized mass protests, boycotts of British goods, and resignations from government positions.

Das presided over the Gaya session of the Indian National Congress. He advocated for council entry and the formation of the Swaraj Party to fight for self-rule from within the legislative councils, a departure from Gandhi's non-cooperation.

Along with Motilal Nehru, Das founded the Swaraj Party within the Indian National Congress. The party aimed to enter legislative councils to obstruct British governance and demand self-rule, marking a shift from boycott to participation.

Das was elected the first Mayor of the Calcutta Municipal Corporation under the reformed municipal act. He used the position to implement welfare measures and assert Indian control over urban governance.
