On August 15, 1947, when India gained independence, Bishnu Prasad Rabha led a black flag demonstration in a village named Dighelia, shouting “Ye Azaadi Jhootha Hain, Sirf Chamra Ka Badal” (This freedom is a hoax : only a change of skin), and he was promptly arrested and put behind bars. After he was released, Rabha went underground for years – presenting a serious challenge to the establishment. He took up arms and engaged in guerrilla warfare against the government.
