The document discusses the growth of indigo cultivation in Bengal under British rule. It summarizes that indigo production expanded rapidly in Bengal in the late 18th century to meet growing demand from Britain's textile industry. Planters used the nij and ryoti systems of cultivation, with ryoti forcing peasants to dedicate a portion of their lands to indigo through exploitative contracts. This led to major peasant unrest and the "Blue Rebellion" of 1859, as peasants refused to grow indigo under oppressive conditions.
