Abstract
When the Japanese invaded Joseon at the end of the sixteenth century, a Spanish Jesuit priest, Gregorio de Céspedes, S.J. , stayed in the Japanese fortress in Ungcheon with Japanese soldiers. While Céspedes is celebrated as the first European who allegedly came with an evangelical vision of proselytizing the native Koreans, previous scholarship has inadequately acknowledged Céspedes’ role without consideration of his concrete actions in the Japanese fortress and of the broader context of sixteenth–century Spanish colonial expansion. An examination of the Jesuit mission to sixteenth-century Japan, the role of the Spanish chaplains and their activities in foreign expeditions, and Céspedes’ activities in Joseon indicate that Céspedes was not a missionary sent to Korea, but rather an active chaplain who played a role in the larger development of church and state collaboration under Spanish colonialism
