The revolutionaries were the first ones to declare a war on the British empire to gain complete freedom. They knew what they wanted but in choosing violent means they were unmindful of the British might and limited support and participation of the public.
The young revolutionaries were inspired by the victories of non-western powers in Japan, Ethiopia and South Africa, and by the revolutions elsewhere. They based their struggle on the socialist ideology and chose sacrifice and violence as the means. They were disillusioned with political mendicancy of the congress and its perpetual failure to get the British government yield to their demands.
They had the energy, vigour and vision that the congress lacked. Had the congress guided them to choose the right path of non-violent protests and wide-spread movement, the nation could have witnessed independence at least a few years earlier.
