Mahatma Gandhi was the notable figure opposing British colonial rule in India. He employed nonviolent resistance as a primary method of mobilizing the Indian populace against British imperialism. Gandhi's philosophy of satyagraha, or "truth-force," advocated for civil disobedience and nonviolent protests as means of achieving political and social change. His leadership in campaigns like the Salt March in 1930 exemplified his strategies, garnering international attention and support for India's independence movement. Gandhi's efforts ultimately contributed to India gaining independence in 1947, and he remains a symbol of peace and resistance worldwide.
