This panel engages emerging field of study anti-communism is as a discrete ideology with transnational character which shaped global politics from the Bolshevik Revolution to the present day. By comparing and contrasting episodes of the instrumentalization of anti-communist politics in different places and historical moments, this panel begins to map out its shared characteristics, as well as its impact. Anticommunism was an ideology with a defined set of ideas and practices, from its role in the Axis to its embrace by the antisemitic American far right in the 1920s and 1930s to its place as an organizing principle for Russian emigres in the immediate aftermath of the Bolshevik Revolution. As this panel demonstrates, anticommunists across the globe shared a language, strategy, and a worldview which profoundly shaped the 20^th and 21^st centuries.
