The Quit India Movement of 1942 was a defining moment in India's fight for independence, driven by rising nationalist sentiment, economic distress, and British repression. Sparked by India's forced involvement in World War II and the failure of the Cripps Mission, the movement called for the immediate end of British rule. Mahatma Gandhi's slogan "Do or Die" galvanized mass participation, with students, women, workers, and peasants taking an active role. The British responded with severe crackdowns, imprisoning leaders and using military force. Despite its suppression, the movement highlighted the resilience of Indian nationalism and exposed the contradictions of British colonialism. It also marked a crucial step toward India's eventual independence in 1947. The active participation of women and rural communities underscored the widespread discontent with British policies. The Quit India Movement, though crushed militarily, succeeded in politically undermining British rule, proving that Indian self-rule was inevitable. The paper explores the movement’s origins, leadership, grassroots involvement, and its impact on India’s independence struggle.
