This study began with the hope of peaceful unification through commu- nication in the culture and arts world, which was completely blocked by differences in ideology between the two Koreas. Through the three dicta- torships, we looked at the evolutionary process of dance and found that the common aspect was the creative form for revolution. Although North Korea's ethnic dance has been transformed into a North Korean folk dance, the unique nature of South Korean works remains. In particular, historical homogeneity could be found in dance using props. It has been confirmed that North Korean dance art was not just an art field, but a means of thought, religion, and political propaganda. It has been con- firmed that the method of inter-Korean exchange becomes culture and art, and I hope this study will serve as a cornerstone for peaceful unification.
