Abstract: | During the height of authoritarianism in South Korea (1972–1979), Christian activists challenged the state along two dimensions. First, protesting Christians formed formal social movement organizations to better garner the resources to sustain their social movement. Second, they waged a discursive battle that challenged the legitimizing rhetoric of the state. By 1979, Christians developed a social movement industry involving the network of formal organizations as well as systematizing their rhetoric of protest in the guise of a Korean liberation theology; Minjung Theology. Drawing upon archival data and social movement theory, this study traces the rise and development of both the Christian social movement industry and Minjung Theology. We find that the emergence and evolution of mobilizing structures and movement frames were influenced by the state's repressive apparatuses and legitimizing rhetoric, respectively. Likewise, Christians’ attempts to mobilize and challenge the legitimizing rhetoric of the state further contributed to the closing of the political opportunity structure. This study empirically verifies recent theoretical work emphasizing the importance of considering the differential impact of repression on various components of a social movement. |
