Nationalism in India

(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. In an effort to win them over the Viceroy, Lord Irwin, announced in October 1929, a vague offer of dominion status. But even this failed to satisfy the leaders.
(ii) Puma Swaraj : In December 1929, under the presidency of Jawaharlal Nehru, the Lahore Congress formalised the demand of ‘Puma Swaraj' or full independence for India. It was declared that 26th January, 1930, would be celebrated as the Independence Day when people were to take a pledge to struggle for complete independence. But the celebrations attracted very little attention. So Mahatma Gandhi had to find a way to relate this abstract idea of freedom to more concrete issues of everyday life.
(iii) 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 assured the Viceroy that he would withdraw the Civil Disobedience on British Government's acceptance of these demands. However, Gandhi's demands were declared to be unrealistic by the Viceroy.
(iv) Economic Causes : The Great Depression of 1929 had a deep impact on the Indian economy, especially on agriculture. Prices of
agricultural produce began to fall from 1926, and collapsed after 1930. As the demand for agricultural goods fell and export declined, peasants found it difficult to sell their harvest, and to pay their revenue. The government refused to lower the taxes. So by 1930, the farmers were in poor condition.
(v) Support from business class :The business class was keen on expanding their business and were against the colonial policies that restricted business activities. They decided to provide financial support to the Civil Disobedience Movement when it was launched.
