Gorigood (a type of shamanistic theatre) is the last of a series of exorcisms in Byulshingood. For the purposes of this study I have focused on the Byulshingood that takes place on the east coast of South Korea. One sub-exorcism called Gori, which is a division of Gorigood, deals with the subject matter of military. This sets it apart from other exorcisms that mostly deal with topics related to sea life. Furthermore, there are two different kinds military-related Gori; one of which is called Goonde gori, pertaining to its military-related theme, and the other of which is called Goongi sagoro joogen gwishin gori`, indicating an exorcism performed with the purpose of soothing a person who died as the result of a military accident. The purpose of this study is to pin-point the reason that this unique military-related exorcism, or Gori`, has found its way into the Gorigood in this region. The results are as follows: Gori` was originally performed by a shamanic group led by Song, Dong-suk, who usually presided over Byulshingood to the north of Pohang. The first reason for the military theme is a geographical one, for the Moogwonyok(巫圈域, the base of a shamanic group) of Song`s shamanic comapany was intensively damaged by North Korea both during the Korean war and during the years 1968 through 1970. The second reason military-related Gori came about was due to frequent communication between South Korean troops stationed on the east coast of South Korea and the local residents. Additionally, Song`s own experience during the Korean war should be taken into consideration, as it surely assisted the assertion of military-related themes into Gori. The third reason considers a theatrical perspective. The military theme plays an effective role in portraying the tragic and comic sides of Gorigood, and also in depicting Oshin(娛神, the act of entertaining a ghost or a spirit) and Wimoo(慰撫, the act of comforting a ghost or a spirit). For this reason also, the `military` might has become a popular topic for shamanistic theatre.
