Popular support for the League of Nations spread around the world in the interwar period but it did not spread evenly. Instead, it was concentrated in white-majority countries: both in Europe and beyond in the form of settler societies around the world. This article explores the relationship between the League movement and white supremacy in one such community: Australia. Citizens in that country combined their allegiance to the League with their beliefs in white supremacy: about the need to restrict immigration through the ‘White Australia’ policy; about the rationale of them ruling over non-white peoples in the territories they held under League ‘mandate’; and about their treatment of Indigenous Australians. In short, they were ‘white internationalists’. Australia’s white internationalists were relatively few. But they reveal a global history of popular white internationalism. Interwar Australians might have been some of the most blatant white internationalists but they were far from the only ones.
