Farmers in Champaran had revolted against indigo cultivation in 1914 (at Pipra) and 1916 (Turkaulia). In April 1917, Mahatma Gandhi visited Champaran, where Raj Kumar Shukla had drawn his attention to the exploitation of the peasants by European indigo planters. The Champaran Satyagraha that followed received support from many Bihari nationalists, such as Rajendra Prasad and Anugrah Narayan Sinha.
