Explanation: The European planters had been forcing the peasants to grow indigo on 3/20 part of the total land (called tinkathia system).

• When towards the end of the nineteenth century German synthetic dyes replaced indigo, the European planters demanded high rents and illegal dues from the peasants to maximize their profits before the peasants could shift to other crops.
• Besides, the peasants were forced to sell the produce at prices fixed by the Europeans.
