Gandhi, Satyagraha and Champaran (source: Wikipedia)

While many civic groups sent petitions and published editorials, Gandhi proposed satyagraha - non-violent, mass civil disobedience. While it was strictly non-violent, Gandhi was proposing real action, a real revolt that the oppressed peoples of India were dying to undertake.
Gandhi also insisted that neither the protestors in Bihar nor in Gujarat allude to or try to propagate the concept of Swaraj, or Independence. This was not about political freedom, but a revolt against abject tyranny amidst a terrible humanitarian disaster. While accepting participants and help from other parts of India, Gandhi insisted that no other district or province revolt against the Government, and that the Indian National Congress not get involved apart from issuing resolutions of support, to prevent the British from giving it cause to use extensive suppressive measures and brand the revolts as treason.

In Champaran
Gandhi established an ashrama in Champaran, organizing scores of his veteran supporters and fresh volunteers from the region. He organized a detailed study and survey of the villages, accounting the atrocities and terrible episodes of suffering, including the general state of degenerate living. Building on the confidence of villagers, he began leading the clean-up of villages, building of schools and hospitals and encouraging the village leadership to undo purdah, untouchability and the suppression of women. He was joined by many young nationalists from the parts and all over India, including Brajkishore Prasad, Dr. Rajendra Prasad, Dr. Anugrah Narayan Sinha and Jawaharlal Nehru.
But his main assault came as he was arrested by police on the charge of creating unrest and was ordered to leave the province. Hundreds of thousands of people protested and rallied outside the jail, police stations and courts demanding his release, which the court unwillingly did. Gandhi led organized protests and strike against the landlords, who with the guidance of the British government, signed an agreement granting more compensation and control over farming for the poor farmers of the region, and cancellation of revenue hikes and collection until the famine ended. It was during this agitation, that Gandhi was addressed by the people as Bapu (Father) and Mahatma (Great Soul).
