This international conference aims to generate comparative and contextualising perspectives on populist nationalism through examining it globally, with a timeframe spanning the ‘long’ twentieth century. The conference’s diverse set of experts will explore how the present relates to the past, considering the relationship between the broad experience of twentieth-century populist nationalism and the challenges and realities of populist nationalism today. The conference also enables a valuable and all-too-rare dialogue between historians and social scientists in examining it.
