The rise of Gandhi as a key figure in the independence movement was influenced by several pivotal events. His experiences in South Africa where he fought against racial discrimination introduced him to nonviolent resistance. Upon returning to India, he mobilized mass protests against British colonial rule through campaigns like the Salt March. Gandhi's philosophies of satyagraha (truth-force) and his ability to unite diverse groups galvanized the Indian population and positioned him as the central figure advocating for Indian independence.
