This paper proposes a theoretical framework to analyzeglobal dimensions of contemporary social movements and attempts to answer the empirical question: why did the social movement for former comfort women emerge in the late 1980s after more than 40 years of silence? The theoretical framework integrates the world polity approach into social movement theory to argue that global political and cultural transformations in recent years have expandedpolitical opportunities at the global level and intensified international flows of mobilizational resources and discursiveframes, increasing the potential for social movements on globally legitimated issues such as human rights. The empirical analysis on the rise and development of the comfort women movement shows that these global factors have been crucial in the emergence and success of the movement. This paper proposes a theoretical framework to understand the impact of newly emerging global norms on contemporary social movements and applies the framework to an empirical case of social movement for former "comfort women." In the past several decades, new normative expectations around progressive issues such as human rights and environmentalism have congealed into fairly coherent global norms and influential international instruments. The progressive ideas have diffused and changed political dynamics across the globe, engendering many new social movements that pressure governments and corporations to change their practice. Scholars in international relations and social movement research have taken notice and produced many studies that examine the impact of the new global norms and institutions on contemporary social movements. This paper builds on this burgeoning literature and seeks a theoretical synthesis of the existing studies on global dimensions of contemporary social movements, incorporating ideas in the world polity research.The theoretical framework will then be applied to a case study on social movements for former "comfort women."' The term "comfort women" refers to an estimated number of 80,000 to 200,000 women who were drafted from the then-Japanese territories with varying degrees of coercion and deception and brought to "comfort stations" to provide sexual services for Japanese soldiers during the Asia-Pacific War (Hicks 1995, Lie 1997, Yoshimi 2000). While women from many of the Japanese colonies were victimized, more than 80 percent of them are said to have been Korean women, making it a particularly thorny diplomatie issue between Japan and Korea (Chai 1993, Soh 1996. They were subjected to coerced sexual labor and terrible living conditions, and their
