Abstract: The Iron Heel by Jack London is a proletarian revolutionary work， reflecting the ideal that the proletariat overthrows the bourgeoisie to achieve the Brotherhood of Man (B.O.M.). Londons shaping of the white masculinity of the character Everhard， the idea of the American Oligarchs integrating the world， and the implication of the American socialists being the dominant force in the realization of B.O.M. are inevitably affected by America’s nationalist ideology during its overseas expansion in the early twentieth century， implying the writers exploration of race， nation and class， etc. From the historical and geopolitical perspectives， the role of imperial discourse in The Iron Heel was explored in the shape of writer identity and national narratives， and the limitations of Londons socialist thoughts were traced.

Key words: Jack London, The Iron Heel, imperial discourse
