The purpose of this study is to examine reports on Lee Bongchang`s patriotic deed by domestic and overseas newspapers published during Japanese occupation from a perspective of critical discourse analysis (CDA) based on their ideological differences. The reports of three selected newspapers were analyzed. One was Maeil Sinbo published by the Japanese government general of Korea, and another was Donga Ilbo, which was a private patriotic newspaper. The third was Shinhan Minbo, which was a Korean newspaper published in the United States. And it`s found that the way of reporting the same incident depended on what position they took and who defined it. The domestic newspapers scaled down this splendid historical incident and reported it negatively from Japanese perspective. It was denounced as a profane incident, and Patriot Lee Bong-chang was labelled as a political offender. These newspapers voluntarily complied with Japanese blackout, which could be called a sort of self-sensorship, and made a contribution to the colonization of people`s consciousness by distorting the incident. On the contrary, however, the overseas newspaper that was free from Japanese press control justified it as a patriotic movement that resisted against imperialism and defined Lee Bong-chang as a righteous hero who fought against evil. Thus, this newspaper highlighted his deed favorably, which was advantageous for Korea.
