The proposed research project has an interdisciplinary focus on the new religions of Korea and Korean nationalist ideologies. Starting with the foundation of Tonghak in 1860, the Korean peninsula has witnessed appearance and rapid growth of a multitude of new religions. Nationalism is an integral theme to Korean new religions, as indicated by the usage of the term ‘minjokjonggyo’ (national religions) to mean new religions. Based on the premise that Korean new religions have been heavily influenced by and have responded to historical and social changes, this research investigates how new religions have maintained and manifested the concepts of Korean ethnic identity and nationalism. Focusing on the era from 1945 liberation up to the end of the Cold War, in light of historical developments and religion-state relationship, I aim to illuminate the changing faces of Korean nationalism and its religious materialisation.
