This book examines three ironic phenomena of South Korean democracy that have developed after its democratic transition in 1987. While the evaluation of South Korea's political system by external institutions has steadily improved, people's trust in the nation's political system continues to decline. However, in the face of political distrust, unlike in Western democracies, voter turnout has increased. Even though political participation and the political influence of citizens have been strengthened over time, the political influence of civic organizations that fostered the initial democratization movement in the 1980s has weakened, parallel to the decline in citizens'confidence in these organizations. Why is South Korean democracy witnessing ironic phenomena that cannot be succinctly explained by existing theories of political development or democracy? This book seeks these answers within the framework of a twotrack democracy, that is, the interplay between institutional and contentious politics. A model of democracy that combines contentious politics with formal politics can shed light on this phenomenon. Yun proposed that the traditional hierarchical and elite-centered political system is no longer sustainable. In order to resolve the democratic deficiency perceived by citizens, it is necessary to consider a new model of democracy beyond the improvement of representative democracy. Moreover, the new model of democracy should be based on a fusion of institutional politics and contentious politics. The book will appeal to scholars and students interested in the politics of South Korea democratization and democracy more generally.
