Mansuseongjeol was originally a term that referred to the birthday of Chinese emperors. In October 1897, when Emperor Gojong ascended the throne, his birthday could be called mansuseongjeol. The celebratory events for mansuseongjeol took place throughout various levels of society and regions. Various places and classes including government officials, foreigners, students, religious people, journalists, merchants, civic groups, and nation-wide open ports celebrated the birth of Emperor Gojong, and the classes celebrating the day became stronger and wider. In other words, in the sense that the celebration had the nature of being universal, national, and global in terms of classes, regions, and races, the event was distinguished. Due to such nature, celebrating culture proceeded in various ways and the imperial family provided donation. Celebration on mansuseongjeol extended to respect toward the emperor and patriotism so it contributed to strengthening the emperor's power and solidifying the unity of the people. Also, such an event was reported around the world through diplomats and reporters living in Korea, raising the national status of Korea in the world. However, after the breakout of Russo-Japanese War, Japan controlled the finance of the royal family, reduced the power of the emperor, and the celebration of mansuseongjeol was also reduced. Due to the suspension of royal family's financial support, crackdown from Japan, and the dethronement of Emperor Gojong, events for mansuseongjeol disappeared and only inside the palace, did formal celebrations continue centering on pro-Japan officials and Japanese people. The abdication of Emperor Gojong came with the collapse of Korean Empire and along with that, celebration of mansuseongjeol came to an end. In the circumstances, the culture of court banquet disintegrated, and the best performers of Korean Empire degenerated into mere entertainers. Though mansuseongjeol, the medium of expressing respect toward the emperor and patriotism, lost its status, it is significant that the cultural achievements, which were created during the process established with the support of the financial power of the royal family, serve as internal power that drove Korea's modern and contemporary cultural history.
