The document summarizes the development of the Indian National Congress between 1920-1922, including its transformation under Gandhi's leadership. Key changes included the introduction of the All-India Congress Committee and Working Committee, reorganizing local committees along linguistic lines, increasing representation of peasants and women, and establishing a system for membership fees and fundraising. In 1920, the Congress adopted a resolution for full independence. This led to the launch of the Noncooperation Movement in 1921, involving boycotts of British goods and institutions like schools and courts. The movement gained strength across India but also had some violent incidents as peasants and workers protested economic issues. Gandhi called off the movement in 1922 after the Chauri Chaura incident of violence.
