The famous Indian leader advocating for non-violent resistance to British rule was Mahatma Gandhi. Born in 1869, Gandhi was a central figure in the Indian independence movement against British colonialism. He promoted the philosophy of Satyagraha, or "truth force," which embraced non-violent protest and civil disobedience as tools for social and political change. His leadership in various campaigns, including the Salt March in 1930, galvanized millions of Indians to participate in the struggle for independence. Gandhi's principles of non-violence and passive resistance have inspired civil rights movements around the world.
