The home rule movements in Taiwan and Korea were two major events that took place at a time when the Taisho Emperor was embracing a more liberal atmosphere. While Taiwan asked for equal standing within the Japanese empire, Korea wanted political independence from colonial rule. The different framing strategies adopted by the social activists lead to the following empirical puzzles: How did the public intellectuals and social activists define their colonial grievances in Taiwan and Korea and seize the window of opportunity in the post-WWI era? And what framing strategies did they apply in promoting their ideas of self-determination?

This article proposes a comparative analysis of Taiwan’s and Korea’s mobilization of international norms, and it investigates how their framing strategies were used in their respective home rule movements during the colonial era. Their rhetoric and mobilization finally led to Japan’s shift to a more conciliatory policy in these two colonies. The finding contributes to the theoretical development of norm contestation and discourse analysis in international relations.

The organizational structure of this article is presented as follows. First, it engages the current literature on social movements, norm diffusion, and East Asian politics, and it explores the framing strategies of the resistance to Japan’s rule by comparing Taiwanese and Korean social movements in the early 1900s. Second, this study offers a framework of norm contestation in capturing how activists in Taiwan and Korea promoted the principle of self-determination. Third, it addresses alternative explanations on the structural factors and agency in these two movements.
