The chapter examines the Czech Repulicans (the SPR-RSČ) , a radical right-wing party represented in the Czech parliament between 1992 and 1998, as a case study of party-based oppositional outsider populism in a consolidating democracy. It traces the origins and development of the party, then examines the populist nature of the party's radical right appeals in the 1990s and the implicit understanding of democracy these contained. It concludes by evaluating the Republicans’ impact on the development of Czech democracy and assessing the extent to which it has left a legacy in contemporary Czech politics
