The Gandhi Sangrahalaya commemorates Mahatma Gandhi's pivotal role in the Champaran Satyagraha of 1917. This movement was a protest against the oppressive indigo plantation system imposed by British landlords on local farmers. Gandhi's arrival in Champaran marked a turning point in his leadership and the Indian independence movement. The museum building itself holds historical significance, having served as a base for Gandhi's activities. It was here that he organized and led the Satyagraha, employing non-violent civil disobedience to fight injustice. The museum preserves the memory of this struggle and Gandhi's connection with Champaran.
