Indian political leader and activist of the early-to-mid 20th century, Gandhi is best known for leading India’s nonviolent struggle against British colonial rule through civil disobedience and moral persuasion. His philosophy of *satyagraha*—firmness rooted in truth—shaped global movements for justice and self-determination.
