This study aims at reevaluating the artistic realism of Choi Seung-hee’s works not only in her full-length dramatic dances after her defection to North Korea but also in her early modern dances with the theme of social participation. The kind of realism that she had pioneered in dance field in 1930 continued into her proletarian dance but discontinued between 1933-1945 due to severe criticism from home and abroad. This study ascribes the undervaluation of her activities in this period to the male mainstream perspective of the society and the decline of proletarian literature. f After her defection to North Korea, Choi’s proletarian dance developed into full-length dramatic dance, which can be referred to as the stage of her completion of socialist realism. The full-length dramatic dance has great meaning in the Korean dance history in that: first, it elevated “dance as art” to a higher level; second, it held a feminist perspective; and third, it achieved a high degree of completion in terms of choreography. Henceforth, Choi Seung-hee’s activities as a pioneering realist dancer in Korea deserves reevaluation in the Korean dance history.
