Indigo revolt was started by the Indigo-producing farmers against imposing more tax on the production of Indigo. Indigo revolt took place between 1858 to 1860 A.D. in a large part of Bengal and Bihar. Farmers of this area refused to produce Indigo. Government threatened them but they remained stick to their demand. When government took some hard steps then they attacked the factories of the British. All the efforts to stop them gone in vain.
One revolt also took place in Champaran district in 1866-68 A.D. against the cultivation of Indigo. This revolt remained continued till the beginning of 20th century. Then Gandhiji came in their favour and then their problem was solved.
