This article explores Yun Ch’i-ho’s studies and social life at Vanderbilt University and Emory College between 1888 and 1893, and the expectations surrounding white Methodists’ investment in his mission to bring Christian and national reform to Korea. Yun’s diary entries document the tensions that existed between late nineteenth-century articulations of white supremacy and, conversely, missionaries’ idealized framing of Christianity as a universally accessible means for uplift, which any race or nation could pursue equally. Yun offers a unique perspective on the era’s global politics of racial identification and on what the alliances and institutional relationships that missionary work necessitated meant personally.
