The upheaval that took place in Bengal immediately after the Revolt of 1857 was the Indigo Disturbances.

The Indigo Disturbances, also known as the Indigo Revolt or Neel Bidroha, occurred in Bengal during the late 1850s and early 1860s. It was a significant agrarian uprising against the oppressive practices of the British indigo planters.

The indigo planters forced Indian farmers, particularly in Bengal, to cultivate indigo on a large scale, leading to exploitative conditions and debt bondage. The farmers were compelled to grow indigo instead of food crops, and they suffered from low wages, high rents, and excessive demands from the planters.

The discontent among the indigo cultivators eventually erupted into widespread protests and rebellions. The farmers organized themselves, refused to cultivate indigo, and actively resisted the planters` attempts to enforce their contracts. The Indigo Disturbances witnessed acts of violence, sabotage, and clashes between the planters and the cultivators.

The Indigo Revolt in Bengal was a significant agrarian movement and one of the important upheavals that followed the Revolt of 1857 in India.
