The Non-cooperation Movement began in 1920, advocating for self-governance and 'Purna Swaraj' after the Indian National Congress withdrew support for the Rowlatt Act. The Civil Disobedience Movement started in 1930 with the Salt Satyagraha and was temporarily halted in 1931, then resumed after the Second Round Table Conference. The Quit India Movement, launched in 1942, demanded an end to British rule following the Cripps Mission's failure.
