Abstract: The India Round Table Conference (London, 1930-32) is presented here as a site of imperial internationalism, at which radical anti-colonialism was subsumed within the liberal technology of the conference. First, the influence of the League of Nations on the conference is examined, through exploring its role as model, precedent, potential arbiter and training ground. Second the paper explores the influence of other (Pan-Islamic, labour and spiritual) forms of internationalism at the London conference. New theorisations of the international are brought to bear on significant new archival and prosopographical material, making an original contribution through revisiting a founding moment in Indian political history.
