What are the three major movements …

1. Champaran:The Champaran agitation in Bihar was Gandhi's first active involvement into Indian freedom politics. The Champaran farmers were being forced to grow Indigo and were being tortured if they protested.

The farmers sought Gandhi's help and through a calculated non-violent protest, Gandhi managed to win concessions from the authority.

2. Kheda: When Kheda, a village in Gujarat, was badly hit by floods, the local farmers appealed to the rulers to waive off the taxes. Here, Gandhi started a signature campaign where peasants pledged non-payment of taxes.

He also arranged a social boycott of the mamlatdars and talatdars (revenue officials). In 1918, the Government relaxed the conditions of payment of revenue tax until the famine ended.

3. Khilafat Movement:

Gandhi's influence on the Muslim population was remarkable. This was evident in his involvement in the Khilafat Movement. After the first World War, the Muslims feared for the safety of their Caliph or religious leader and a worldwide protest was being organised to fight against the collapsing status of the Caliph.

Gandhi became a prominent spokesperson of the All India Muslim Conference and returned the medals he had received from the Empire during his Indian Ambulance Corps days in South Africa. His role in the Khilafat made him a national leader in no time.

4. Non-cooperation Movement

Gandhi had realised that the British had been able to be in India only because of the co-operation they received from the Indians. Keeping this in mind, he called for a non-cooperation movement.
