In 2023, Korean government announced it policy plan that it would pursue the preservation of provincial cities’ status through regional culture’s development, generating cities with their own regional culture which can attract more population. Such aim can be deemed as the attempt to solve social problem through the value of regional culture. But among all regional-culture elements, the discovery and attraction of historical materials shall be the shortcut for enhancement of regional cultural value. In this study, among regional-history performance contents, that of Jeam-ni massacre — the event having occurred in line with Hwaseong’s independence movement, which had been influenced by March First Independence Movement —, was analyzed. Through this study, Given that, focusing on the musical “The Monuments Differing in Heights”, I revisited the case of Jeamni massacre, and explored how its historical facts were ascertained and were made as the play. Doing so, I reviewed how its musical elements were developed and applied, and how the historical narrations were realized in the stage with limited time and space. With all those, the following conclusions were drawn out. First, the regional-history performance contents do have education values, because they re-interprete narration based on historical ascertaining, making people recognize again about real historical events. Secondly, the production process of those performances needs to be more systemized. That is, I could re-establish the production system by reviewing the process through which the historical performance contents were developed within the frame of general performance production. Thirdly, the processes and results of performances which deal with regional history should be more dataficated. If such datafication is achieved, the continuous development of initially-made performances can be facilitated, by which those works will be able to settle as regional cultural contents. With all those, it is expected that this research shall serve as an important material for groups and individuals who are engaged in performance contents on regional history, by which our historical performance contents can have more globalized effect.
