Abstract: | This study aims to provide insights into how and why a dominant party system emerges after an era of multipartyism. Conceptualising the emergence phase of a dominant party system within the framework of Sartori's ‘predominant party system’, it elaborates the causal weight of different theories within the Turkish context through a comparative-historical analysis. Comparing the case of the Justice and Development Party (AKP) with the Justice Party (AP), it argues that perceptions of an incumbent's good economic performance and lack of centrifugal intra-party conflicts are two crucial factors that lead to the emergence of a dominant party system after multipartyism. Restrictive electoral rules and existing social cleavages, however, create a favourable setting for this outcome. |
