Long term impact

Salt Satyagraha produced scant progress toward dominion status or independence for India, and did not win any major concessions from the British.[63] It also failed to attract Muslim support—many Muslims actively boycotted the satyagraha.[64] Congress leaders decided to end satyagraha as official policy in 1934. Nehru and other Congress members drifted further apart from Gandhi, who withdrew from Congress to concentrate on his Constructive Programme, which included his efforts to end untouchability.[65] Even though British authorities were again in control by the mid 1930s, Indian, British, and world opinion increasingly began to recognize the legitimacy of claims by Gandhi and the Congress Party for independence.[66] The Satyagraha campaign of the 1930s also forced the British to recognize that their control of India depended entirely on the consent of Indians — Salt Satyagraha was a significant step in the British losing that consent.[67]
Nehru considered Salt Satyagraha the high water mark of his association with Gandhi,[68] and felt that its lasting importance was in changing the attitudes of Indians:
Of course these movements exercised tremendous pressure on the British Government and shook the government machinery. But the real importance, to my mind, lay in the effect they had on our own people, and especially the village masses....Non-cooperation dragged them out of the mire and gave them self-respect and self-reliance....They acted courageously and did not submit so easily to unjust oppression; their outlook widened and they began to think a little in terms of India as a whole....It was a remarkable transformation and the Congress, under Gandhi's leadership, must have the credit for it.[4]
More than thirty years later, Satyagraha and the March to Dandi exercised a strong influence on American civil rights activist Martin Luther King, Jr., and his fight for civil rights for blacks in the 1960s:
Like most people, I had heard of Gandhi, but I had never studied him seriously. As I read I became deeply fascinated by his campaigns of nonviolent resistance. I was particularly moved by his Salt March to the Sea and his numerous fasts. The whole concept of Satyagraha (Satya is truth which equals love, and agraha is force; Satyagraha, therefore, means truth force or love force) was profoundly significant to me. As I delved deeper into the philosophy of Gandhi, my skepticism concerning the power of love gradually diminished, and I came to see for the first time its potency in the area of social reform.[9]
