O'Donovan Rossa took up residence in New York City, where he joined Clan na Gael and the Fenian Brotherhood. Rossa additionally established his own newspaper dedicated to the cause of Irish national liberation from British rule, "The United Irishman." In it Rossa advocated the terroristic use of dynamite bombs as a means of overthrowing the British occupation. His paper was used to raise a so-called "resources for civilisation fund," presumably for the purchase of dynamite and other armaments for the Irish struggle.
