The influential Indian leader known for promoting non-violent resistance against British rule was Mahatma Gandhi. His philosophy of Satyagraha emphasized peaceful protest as a means to achieve political and social reform. Gandhi's approach mobilized millions and garnered international attention to India's struggle for independence. He advocated for civil disobedience and empowered the masses by encouraging them to withdraw support from British authorities. His leadership became a defining force in the Indian independence movement, ultimately leading to India's freedom in 1947, and inspired similar movements for justice and equality worldwide.
