Following were the two causes that led to the Civil Disobedience Movement:
(i) Failure of the Simon Commission: The Simon Commission was constituted in response to the nationalist movement. But the Commission failed to satisfy the Indian people and the leaders. All the parties, including the Congress and the Muslim League, participated in the demonstrations.
(ii) Rejection of Gandhi's Eleven Demands: On 31‌st ‌ January, 1930, Mahatma Gandhi, in a statement, put forward eleven demands to correct the wrongs done to the Indians. He cautioned the Viceroy that the Congress would launch a civil disobedience campaign, if these demands were not fulfilled by 11‌th ‌ March, 1930 . However, Gandhi's demands were declared to be unrealistic by the Viceroy.
