Gandhi ji, also known as Mahatma Gandhi, was a prominent leader of the Indian independence movement against British rule. During his activism, he fought for the rights of farmers who were being exploited by the indigo planters in Champaran, Bihar, India.

Gandhi ji's involvement in the Champaran Satyagraha movement in 1917 aimed to address the grievances of the indigo farmers. The indigo planters forced the farmers to cultivate indigo on their lands and then sell it to them at very low prices, leading to severe economic exploitation.

To address this issue, Gandhi ji demanded fair compensation for the farmers from the indigo planters. The specific amount he asked the planters to pay was not a fixed percentage but rather a specific amount per acre of land cultivated with indigo. The demand was for the planters to pay Rs. 25 per acre to the farmers.

This demand was significant because it aimed to provide a fair and just remuneration to the farmers for their labor and prevent their exploitation by the planters. It also sought to challenge the unjust and oppressive system of indigo cultivation that had been prevalent in the region.

Gandhi ji's demand for Rs. 25 per acre was based on his understanding of the economic conditions of the farmers and the value of their labor. He believed that this amount was fair and reasonable, considering the hardships faced by the farmers and the profits earned by the planters from the indigo trade.

By demanding fair compensation for the farmers, Gandhi ji aimed to empower them and improve their economic conditions. This demand was an important aspect of the Champaran Satyagraha movement, which ultimately led to the abolition of the oppressive indigo system and brought attention to the plight of farmers in India.

In conclusion, Gandhi ji demanded Rs. 25 per acre from the indigo planters as fair compensation for the farmers. This demand aimed to address the economic exploitation faced by the farmers and played a significant role in the Champaran Satyagraha movement.
