The advent of synthetic indigo had a profound impact on the Champaran sharecropping system, as detailed in the chapter Indigo from Class 12th. Synthetic indigo, produced through chemical processes, significantly reduced the demand for natural indigo cultivated by the peasants, leading to a decline in its market value. This shift threatened the economic viability of the farmers who were already struggling under the burdens of oppressive landlords and the exploitative sharecropping system. As a result, many peasants faced increasing poverty and uncertainty about their livelihoods, intensifying the urgency of their struggle for rights and justice in the Champaran region.
