Gandhi's arrival in Champaran spread quickly. He surveyed the situation of poor peasants who were forced to grow indigo and surrender their harvests as rent to British landlords. When Gandhi was ordered to leave, he refused, disobeying authorities for the first time. Over a year, Gandhi gathered evidence of injustice and secured a commission to investigate. This led to landlords refunding 25% of payments and freeing peasants from unfair contracts, establishing civil disobedience as a tactic for independence struggles.
