This thesis aims to provide a view point from which we can understand the long-term historical transformations of Korean politics since the late fourteenth century. I will attempt to illustrate the overall configuration of Korean politics with sociological reference to three questions: what kinds of political events have occurred? Which political issues have led to the participation of major political actors? How have these actors shown their political orientation in practice and how have events and actors determined politics, or, if there is no determination, how have they influenced the overall shape of politics? The concept of modernity in this thesis is mainly used to indicate the embodiment of political actors' alternative visions without necessarily accepting the widely acknowledged assumption that modernity is the epochal quality of the contemporary period which exclusively enjoy. Some sociologists, especially in comparative-historical sociology, since the late 1990s have shown their intellectual interest in conceptualizing 'multiple modernities'. They recognize the importance of theorizing the existence of plural forms of societal development for the contemporary situation, while some classical ideas on modernity based on the European or American experience have been critically evaluated in regional studies. If the Korean experience is regarded as an example of multiple modernities, it is not because the political boundary itself - which has been called Korea, as well as Chosun, Koryo, Balhac/Shilla, etc. -, has its own distinctive political and cultural color. Rather it is because the actors in Korean history generally, have shown themselves to be a good example for evaluating modernity. Regardless of quite different historical trajectories, the compatibility of the Korean experience with others under the title of multiple modernities, can be adduced both from the way in which human practices have emerged in their collective form, with their own political orientations, and in the relationship to other actors within a boundary.
