Regionalism
This chapter examines regional division, or regionalism, in South Korea, a dominant factor determining the country’s politics. The conceptual definition of regionalism in the context of South Korean politics refers to regional patterns of voting behaviour, with voters deciding their vote based on their birthplace. But regionalism has been also understood from different perspectives focusing on its history, public emotional antagonism, regional party system, etc. This chapter elaborates the origins of regionalism and conceptualizes regionalism according to the level of analysis and the domain of its manifestation. The chapter then promotes the theoretical understanding of regionalism by drawing on prejudice, social identity, and cleavage theory. It argues that the regional cleavage based on birthplace-based regional prejudice and identity that have determined electoral behaviour and party system will not change significantly in the near future. The chapter concludes with a discussion of recent developments in regionalism.
