Gandhiji came to know about the share croppers plight at Champaran. There the landlords forced the peasants to plant indige on 15% of the holdings and all the harvest was to be surrendered to the planters as rent. They were also signing contracts for the compensation under compulsion. Gandhi held a demonstration against the government. The officials became helpless and the government was helped. A settlement was reached. The share croppers got 25% of their money back. In this way Gandhiji helped the peasants of Champaran.

Gandhiji played a pivotal role in helping the peasants of Champaran in Bihar. His efforts were aimed at fighting for their rights and securing justice for them.

By fighting and securing justice for them:
- In 1917, Gandhiji visited Champaran after being approached by the local peasants who were suffering under the oppressive system of indigo cultivation imposed by the British landlords. He decided to take up their cause and fight for their rights.
- Gandhiji organized a detailed investigation into the grievances of the peasants, interacting with them and collecting evidence about their exploitation.
- He gathered information about the forced cultivation of indigo and the exorbitant taxes imposed on the peasants, along with their inhumane living conditions.
- Gandhiji then launched a non-violent resistance movement against the British landlords and the British administration, demanding justice for the peasants of Champaran.
- He mobilized the local peasants, educating them about their rights and encouraging them to stand up against the unjust system.
- Gandhiji also involved lawyers in the movement, who provided legal support to the peasants and helped them fight their case in court.
- Through his efforts, Gandhiji was able to draw significant attention to the plight of the peasants in Champaran, both within India and internationally.
- Eventually, the British government was compelled to appoint a commission to investigate the matter.
- The commission's report vindicated the peasants' claims, leading to the abolition of the oppressive indigo system and the implementation of reforms that improved the peasants' living conditions.

In conclusion, Gandhiji's fight for justice for the peasants of Champaran involved organizing a non-violent resistance movement, educating the peasants about their rights, and securing legal support for their case. Through his efforts, he was successful in bringing about significant changes and improving the lives of the peasants.
