New political parties are an object of interest in many studies, either in the form of theoretical anchoring to relevant concepts or in the search for further theoretical overlaps. However, there is not a general agreement in political parties’ research on exactly how to classify a new political party and how precisely newness is measured and captured. New parties may be an important element in analysing the party system’s entire transformation. Th is text is a discussion paper to introduce and debate various analytical perspectives on the analysis of new parties, that have not yet achieved much in the Czech environment. In addition to the current state of knowledge, three major problems will be outlined, such as the absence of a generally accepted defi nition of a new political party, the applicability of diff erent theoretical frameworks, and the question of continuity or discontinuity of individual new or established actors. Th e text aims to discuss the possibilities of measuring novelty as a dichotomous variable. Each of the presented approaches has its advantages and pitfalls, depending on the empirical reality and the justifi cation of the author’s preferred analytical approach.
