However, many disintegrate soon after recording their parliamentary breakthrough, but some manage to survive and establish themselves in their party systems. What can explain these contrasting fates? First, a brief review of the available literature on the topic is presented and various theories are examined, which leads to the specification of the research question: “Does the homogeneity of party elites’ social backgrounds increase the likelihood of new party survival?” This thesis aims to contribute to the empirical research on the survival of new parties and answer the research question using a qualitative analysis of an extensive dataset of party elites’ social backgrounds in five new political parties in Slovakia. The research did not find compelling evidence to support the hypothesis that the homogeneity of party elites’ social backgrounds increases the likelihood of new party survival. The thesis concludes by discussing the reasons for this, explores alternative explanations, addresses its limitations and identifies areas for further research.Show less
