Sport has important political power in contemporary culture. When North and South Korean athletes marched under a unified flag during the opening ceremonies of the 2018 Winter Olympics in PyeongChang, South Korea, it provided a powerful sign of cooperation between the two nations. Seeing the two Koreas marching together symbolized hope for reunification in the Korean peninsula. The 2018 Olympics, however, were only one chapter in a much longer story about the ways in which South Korea has invested substantial resources in attempts to foster a (global) Koreanness through success in sporting mega-events. In fact, cultural anthropologist Rachael Miyung Joo has argued that South Korea sees transnational sport as the most useful way to demonstrate the potential of a “global Korea.” Sport, in this respect, is used as a cultural apparatus to build a collective identity—what political scientist Benedict Anderson called an “imagined community.” Here, we aim to deconstruct South Korean sporting nationalism by analyzing how sport operates to establish and reinforce nationalism in South Korea.
