Mahatma Gandhi spearheaded the Non-Cooperation Movement from 1920 to 1922, engaging millions of Indians nationwide. This movement pursued a strategy of nonviolent opposition to British governance through boycotts of British merchandise, educational institutions, and public services. The broad involvement of various social strata, such as farmers, scholars, and laborers, was instrumental in eroding British power. This extensive participation and unified action advanced India's journey towards autonomy.
