|(1) Failure of Cripps Mission- The offers made by the Cripps Mission and its subsequent failure made it clear to the leaders that the British government was not willing to offer any concrete settlement. She was rather more interested in forcing India to support its war efforts. Even Gandhi and Nehru, who were against the Fascist and Nazi governments, began to feel that being a silent spectator would simply mean accepting the fact that the decision regarding the political fate of India was only in the hands of the British. Gandhi, who was against the idea of hampering the war efforts of the British against Germany and Italy, also began to feel the necessity of a non-violent struggle.|
(2) Japanese posed a threat to India- During World War, Japan was on the side of the Axis Powers. On December 7, 1941, Japan attacked Pearl Harbour, an American naval base in Hawaii Island, which caused anxiety to Britian, the USA and China. Then Japan overran the Philippines and Malaya. In February 1942 the Japanese seized Singapore. After occupying Myanmar (Burma), they marched towards Assam. Gandhiji observed, “The presence of British in India is an invitation to Japan to invade India. Their withdrawal removes the bait”. Some Congressmen did not agree with Gandhiji about starting a mass agitation during the course of the war. However, they agreed to abide by his decision; and those who did not agree (like C. Rajagopalachari) quit the Congress. The threat of a Japanese attack on India because of the presence of the British was one of the important reasons for launching the Quit India Movement.
(3) Popular Discontent- Prices of foodgrains were rising up almost 60-point rise in eastern U.P. between April and August 1942. There was also a shortage of rice and salt. During the crisis of food grains, the Indian market was left in the hands of black marketers, and profiteers which affected the poor most, especially in eastern India. The Congress leaders felt that the time has arrived to give direction to the general discontent among the masses.
(4) Racial Character of the British Empire- The manner in which the British evacuated Malaya and Burma exposed the real character of the British Empire. The British, in these colonies, evacuated the white residents and left the local population to their own fate. It exposed the racial character of the British.
(5) Other Causes- (I) There was anger and hostility towards meaningless war especially when thousands of wounded soldiers returned from the Burmese war. (II) The arrogance of the British, Americans and Australians, the maltreatment of Indian people, particularly incidents of rape, made the grievances even more forceful. (III) Japanese success story in South-East Asian countries demystified the superiority of Europeans especially English.
