Swaraj and the Salt Satyagraha (Salt March)

Gandhi at Dandi, 5 April 1930, at the end of the Salt March.

Gandhi stayed out of active politics and as such limelight for most of the 1920s, preferring to resolve the wedge between the Swaraj Party and the Indian National Congress, and expanding initiatives against untouchability, alcoholism, ignorance and poverty. He returned to the fore in 1928. The year before, the British government had appointed a new constitutional reform commission under Sir John Simon, which did not include any Indian as its member. The result was a boycott of the commission by Indian political parties. Gandhi pushed through a resolution at the Calcutta Congress in December 1928 calling on the British government to grant India dominion status or face a new campaign of non-cooperation with complete independence for the country as its goal. Gandhi had not only moderated the views of younger men like Subhas Chandra Bose and Jawaharlal Nehru, who sought a demand for immediate independence, but also reduced his own call to a one year wait, instead of two. The British did not respond. On 31 December 1929, the flag of India was unfurled in Lahore. 26 January 1930 was celebrated by the Indian National Congress, meeting in Lahore, as India's Independence Day. This day was commemorated by almost every other Indian organization. Gandhi then launched a new satyagraha against the tax on salt in March 1930, highlighted by the famous Salt March to Dandi from 12 March to 6 April, marching 388 kilometres (241 miles) from Ahmedabad to Dandi, Gujarat to make salt himself. Thousands of Indians joined him on this march to the sea. This campaign was one of his most successful at upsetting British hold on India; Britain responded by imprisoning over 60,000 people. The government, represented by Lord Edward Irwin, decided to negotiate with Gandhi. The Gandhi–Irwin Pact was signed in March 1931. The British Government agreed to set all political prisoners free in return for the suspension of the civil disobedience movement. As a result of the pact, Gandhi was also invited to attend the Round Table Conference in London as the sole representative of the Indian National Congress. The conference was a disappointment to Gandhi and the nationalists, as it focused on the Indian princes and Indian minorities rather than the transfer of power. Furthermore, Lord Irwin's successor, Lord Willingdon, embarked on a new campaign of controlling and subduing the movement of the nationalists. Gandhi was again arrested, and the government attempted to negate his influence by completely isolating him from his followers. However, this tactic was not successful.

In 1932, through the campaigning of the Dalit leader B. R. Ambedkar, the government granted untouchables separate electorates under the new constitution. In protest, Gandhi embarked on a six-day fast in September 1932, successfully forcing the government to adopt a more equitable arrangement via negotiations mediated by the Dalit cricketer turned political leader Palwankar Baloo. This was the start of a new campaign by Gandhi to improve the lives of the untouchables, whom he named Harijans, the children of God. On 8 May 1933 Gandhi began a 21-day fast of self-purification to help the Harijan movement. This new campaign was not universally embraced within the Dalit community, however, as prominent leader B. R. Ambedkar condemned Gandhi's use of the term Harijans as saying that Dalits were socially immature, and that privileged caste Indians played a paternalistic role. Ambedkar and his allies also felt Gandhi was undermining Dalit political rights. Gandhi, although born into the Vaishya caste, insisted that he was able to speak on behalf of Dalits, despite the availability of Dalit activists such as Ambedkar.

In the summer of 1934, three unsuccessful attempts were made on his life.

When the Congress Party chose to contest elections and accept power under the Federation scheme, Gandhi decided to resign from party membership. He did not disagree with the party's move, but felt that if he resigned, his popularity with Indians would cease to stifle the party's membership, that actually varied from communists, socialists, trade unionists, students, religious conservatives, to those with pro-business convictions and that these various voices would get a chance to make themselves heard. Gandhi also did not want to prove a target for Raj propaganda by leading a party that had temporarily accepted political accommodation with the Raj.

Gandhi returned to the head in 1936, with the Nehru presidency and the Lucknow session of the Congress. Although Gandhi desired a total focus on the task of winning independence and not speculation about India's future, he did not restrain the Congress from adopting socialism as its goal. Gandhi had a clash with Subhas Bose, who had been elected to the presidency in 1938. Gandhi's main points of contention with Bose were his lack of commitment to democracy, and lack of faith in non-violence. Bose won his second term despite Gandhi's criticism, but left the Congress when the All-India leaders resigned en masse in protest against his abandonment of the principles introduced by Gandhi.
