Founded in 1932, the Perkonkrusts (“Thunder Cross”) was the largest and most prominent right-wing political party in Latvia in the early twentieth century.Its motto—“Latvia for Latvians!”—echoed the ultranationalist rhetoric of similar movements throughout Europe at the time.Unlike the Nazis in Germany or the Fascists in Italy, however, the Perkonkrusts never succeeded in seizing power.Nevertheless, Holocaust historian Paula A. Oppermann argues, its movement left an indelible mark on the country.The antisemitism at the core of the Perkonkrusts’ ideology remained a driving force for Latvian fascists throughout the twentieth century, persisting despite shifting historical and political contexts. Thunder Cross is the most comprehensive study of Latvia’s fascist movement in English to date, and the only work that investigates the often neglected continuities of fascist antisemitism after World War II.Formulated as an empirical case study, this book draws on international and interdisciplinary secondary literature and sources in seven languages to broaden our understanding of fascism, antisemitism, and mass violence from Germany and Italy to the larger European context.
