Answer the following questions in one sentence.

Where did Gandhiji launch the first satyagraha in India?

Gandhiji launched his first Satyagraha Movement in the district of Champaran in 1917. Champaran is a district in Bihar. Under British law, farmers were forced to grow Indigo on a portion of their land as a condition of their tenancy. Indigo was then used to make dye. The Germans had invented a cheaper artificial die, so the demand for Indigo fell. The farmers then had to pay more rent in return, if they did not want to grow Indigo. During the first World War, the German dye ceased, and Indigo became profitable again. Again the Indian farmers were forced to grow it. Gandhiji then organized protests and strikes and formed his first satyagraha for the same. It was also called Champaran Satyagraha.
