Its objective was to establish a “Federated Republic of the United States of India” through an organized and armed revolution.
These young men did not like the theory of nonviolence. They had confidence that the British can be thrown out of the country by using of force and violence. At the same time, there were uprisings in other parts of world and one could witness a number of bloody revolutions and coupe de etat around the word. The result was that the old Yugantar and Anushilan samiti got awaken and a new breed of terroristic kind of revolutionaries emerged from the unenthusiastic and unsatisfied Non-cooperators.
The name was chosen as Hindustan Republican Association on the lines of Irish Republican Army. The manifesto of this revolutionary organization was “The Revolutionary“.
