The first major Satyagraha movement led by Mahatma Gandhi in India took place in Champaran in 1917. This movement was a significant event where Gandhi applied his philosophy of non-violent resistance to address agricultural laborers' grievances. Champaran, located in Bihar, was where farmers were struggling under oppressive conditions imposed by the British planters. The success of this movement marked a turning point in the Indian independence struggle, showcasing the efficacy of Satyagraha in transforming social and political injustices through peaceful means.
