Bose was elected president of the Indian National Congress for two consecutive terms but resigned from the post following ideological conflicts with Mahatma Gandhi. Bose believed that Mahatma Gandhi's tactics of nonviolence would never be sufficient to secure India's independence, and advocated violent resistance. He established a separate political party, the All India Forward Bloc and continued to call for the full and immediate independence of India from British rule. He was imprisoned by the British authorities eleven times. His stance did not change with the outbreak of the Second World War, which he saw as an opportunity to take advantage of British weakness.
