This paper examines the life and national independence activities of Han Wui-geon(韓偉健), who was one of the student leaders of the March First Independence Movement. A sophomore of Gyeongseong Medical College, he led the students of the school to Pagoda Park to participate in the Declaration of Independence and the street demonstration. He then fled to Shanghai, and participated in the Provisional Government of the Republic of Korea. Han came to Japan in 1920. In October of the same year, he joined the Communist Research Institute and worked as a member of the Joseon Student Association and director of the Joseon YMCA. In 1923, he carried out activities to investigate the massacre of Koreans and criticize the Japanese government's responsibility. He returned to Korea in the fall of 1924 and worked for Shi-Dae Ilbo and Dong-A Ilbo. Later, he was elected as a central committee member of the Korean Communist Party and became a founding member of Singanhoe. Back in China, Han joined the Communist Party of China in 1931. With his wife, he was expelled from the Chinese Communist Part for his “rightism“ but later was reinstated. He died of tuberculosis and typhoid fever in 1937. In 1940, the Communist Party of China approved the legitimacy of his line and erected a tombstone for him in 1945.
