The first significant modern theatre movement in Korea arose in the early 1920s. Modern Irish drama and its theatre movement has always been a major field of interest for the Korean intellectuals and dramatists who believed that it provided a model for the modern Korean theatre. The importation of Irish drama was systematically conducted by different groups from the Korean intellectuals in the 1920s and 1930s, during which period many of them published articles concerning Irish drama and the Irish theatre movement. A famous Korean writer Hyo-Seok Lee(1907-1942) published an article titled 'A Research about John Millington Synge's Drama' in 1930, a compressed version of his BA degree essay in Monthly Dae-joong-gong-ron(Public Opinion). However, despite of his fame and popularity as a writer and material for academic research, this article has been forgotten and has remained unknown. Majority of Korean scholars concentrate on Lee's novel and essays while comparatively neglecting Lee's interest towards Irish drama. The main areas of discussions are the followings. First, socio-cultural significance of Irish impact on Korean theatre will be discussed. Second, in the context of Irish influence on Korean drama, the main feature of Lee's viewpoint towards Synge will be examined in comparison with other politically oriented Korean essays.
