Statement:

 The Champaran movement started because the farmer was forced to grow cotton on their land.

Farmers were compelled to cultivate indigo on their property, which sparked the Champaran movement. Attracted by India's cotton belts during the British era, cotton was eventually supplied to Britain as a raw material for their textile industry. The availability of high-quality cotton from India allowed the cotton textile industry in Manchester and Liverpool to develop. You've read about the Champaran movement, which got its start in Bihar in 1917. Due to the indigo's necessity for the textile industries in Britain, this was initiated by the local farmers who were compelled to cultivate it on their land.
