The year 2019 is the centennial of several anti-colonialist movements that emerged in Asia, including the March First Movement of Korea, the first nationwide political protest in Korea under Japanese colonial rule. Although the movement failed to achieve national sovereignty, it left important legacies for Korea and other parts of Asia under foreign dominance. In this essay, Gi-Wook Shin and Rennie Moon discuss the origins of the March First Movement, its impact on colonial Korea and other parts of Asia that fought against imperialist dominance, and its implications for postcolonial and contemporary Korea, North and South.
