In 1982, a group of writers and musicians gathered in Gwangju to clandestinely perform “March for the Beloved” (Im ŭl wihan haengjin-gok), a song created to honor the “soul marriage” of two activists who had died in the Kwangju Uprising two years prior. Over the following decades, the song emerged as a central piece in South Korea’s repertoire of resistance, resurfacing in March 2017 during months of sustained popular demonstrations that led to the impeachment of Park Geun-hye. And beyond South Korea, the song would become a call to action in various other parts of Asia, including Hong Kong, China, Japan, Malaysia, and Thailand. This paper examines the role that the Gwangju Uprising played in the process of South Korea’s democratization, and argues that “March for the Beloved” was instrumental in transforming the victims of state violence into martyrs and the subalterns of an unlawful republic into political subjects of a morally righteous counter-republic. This paper analyzes the people-oriented cultural practices behind the birth of the song, as well as the performative elements in the making of the song into an anthem of the counter-state. In conclusion, the paper discusses the ongoing controversy over the song as an occasion to think about the reification of Gwangju and the perpetual struggle over its signification in South Korea’s contemporary moment.
