Champaran is a place in Chhattisgarh, which is a state in India. Champaran became famous for a historical event called the Champaran Satyagraha, which happened a long time ago.
Before Champaran Satyagraha, many farmers were growing indigo plants in Champaran. The British people who ruled India at that time forced the farmers to grow indigo plants because it was profitable for them. The farmers had no choice but to grow indigo plants, and they had to sell it to the British at a very low price. This left the farmers with barely enough money to survive.
But one day, a man named Mahatma Gandhi heard about the sad conditions of the farmers in Champaran. He decided to go to Champaran and help them. When he reached Champaran, he saw that the poor farmers were being treated unfairly, and he knew he had to do something.
He convinced the farmers to stop growing indigo plants and grow food crops instead. But the British people did not like this idea because it was not profitable for them. They arrested Gandhi, which made the people even more angry.
But Gandhi did not give up. He went on with peaceful protests, and finally, the British had to listen to him. This was the first victory of Gandhi's non-violent movement in India.
In the end, the British had to change their policies, and the farmers were free to grow whatever crops they wanted. This helped the farmers gain more income and live a better life. Champaran became a symbol of hope and freedom for many people.
