Which key principle of Gandhis philosophy was first applied in Champaran?

The key principle of Gandhi’s philosophy that was first applied in Champaran was nonviolent resistance, also known as Satyagraha, as described in the chapter Indigo from Class 12th. This approach emphasized peaceful protest and civil disobedience as means to confront injustice and oppression without resorting to violence. Gandhi’s application of Satyagraha in Champaran involved mobilizing the indigo farmers to stand up against the exploitative practices of British landlords through collective action and moral strength. This foundational principle not only guided the Champaran Movement but also became a cornerstone of India’s broader struggle for independence, demonstrating the power of nonviolent action in effecting social change.
