The Indigo Revolt (Nil Bidroho) occurred in Bengal in 1859-60, primarily against European indigo planters who forced peasants to cultivate indigo against their will and under oppressive conditions. The revolt received significant support from various sections of Bengali society, including some zamindars (who were also often exploited by planters), village headmen (mukhtars), and notably, the educated Bengali intelligentsia. Journalists like Harish Chandra Mukherjee highlighted the plight of the peasants in the 'Hindoo Patriot', and the play 'Nil Darpan' by Dinabandhu Mitra exposed the brutality of the planters, stirring public opinion.
