- The Non-Cooperation Movement (1920-1922) was launched by Mahatma Gandhi following events like the Jallianwala Bagh massacre and the Rowlatt Act. - A key objective of this movement was to withdraw Indian cooperation from the British government as a form of peaceful protest against their rule. - The program included the surrender of titles and honorary offices, resignation from nominated posts in local bodies, boycott of government and government-aided schools and colleges, boycott of law courts, boycott of foreign goods, and renunciation of government services and participation in elections.
