After World War I, Slovakia became part of the new country of Czechoslovakia. In both parts of the new republic, anti-Jewish riots broke out in the aftermath of the declaration of independence (1918–1920), although the violence was not nearly as serious as in Ukraine or Poland. Blood libel accusations occurred in Trenčin and in Šalavský Gemer in the 1920s. In the 1930s, the Great Depression affected Jewish businessmen and also increased economic antisemitism. Economic underdevelopment and perceptions of discrimination in Czechoslovakia led a plurality (about one-third) of Slovaks to support the conservative, ethnonationalist Slovak People's Party (: HSĽS). HSĽS viewed minority groups such as Czechs, Hungarians, Jews, and Romani people as a destructive influence on the Slovak nation, and presented Slovak autonomy as the solution to Slovakia's problems. The party began to emphasize antisemitism during the late 1930s following a wave of Jewish refugees from Austria in 1938 and anti-Jewish laws passed by Hungary, Poland, and Romania.
