ABSTRACT
This chapter seeks to answer the questions: how could the radical groups survive despite their militant tactics and ideology how were they able to form a cooperative relationship with moderate groups by tracing the evolving relations within the broader social movement sector in post-authoritarian South Korea. It focuses on how many South Korean movement groups utilized coalition as an organizational vehicle in many protest campaigns. The chapter locates the characteristics of coalitions in post-authoritarian South Korea within a broader conceptual field. It uses the concept of "repertoire" and highlight how coalition can be understood as a historical product based on successive choice-making. The chapter illustrates how democratic transition provided new opportunities for mass-based popular organizations to emerge on an unprecedented scale while the conservative nature of transition kept these organizations systematically excluded from the institutionalized political process, resulting in radicalization of these groups. It discusses how radicalization of the movement sector facilitated a crisis of the minjung movement.
