Explanation: In Bengal, the indigo planters, nearly all Europeans, exploited the local peasants by forcing them to grow indigo on their lands instead of the more paying crops like rice.

• The planters forced the peasants to take advance sums and enter into fraudulent contracts which were then used against the peasants.
• The anger of the peasants exploded in 1859 when, led by Digambar Biswas and Bishnu Biswas of Nadia district, they decided not to grow indigo under duress and resisted the physical pressure of the planters and their lathiyals (retainers) backed by police and the courts.
