This paper tackles the issue of the reverse proportion between nationalist movement and social revolution, which characterizes Irish revolutionary movements depicted in Roddy Doyle’s A Star Called Henry. The most salient of Henry Smart’s heroic actions, mythologized aspects of which are told to parody those of legendary warriors in Celtic myths, is his proletarian performance grounded in his socialist disposition. It is argued in this paper that the mythicized Henry evokes the revolutionary passions of workingmen in the 1913 Dublin Lockdown, the 1916 Rising, and the ensuing Irish War of Independence. Henry is a verisimilar incarnation of the historical James Connolly, who was a forerunner of Irish socialism, in the way of reinstating a proletarian position in the movement of national independence. Henry is Doyle’s artistic hyperbole for constructing the internal exigencies of workingmen propelled to prioritize social revolution over national independence. Henry’s proletarian heroism has the prospect of the national independence followed by the liberation of the working class, the most deprived of social classes.
