The Joseon Anti-Communism Association, founded on August 15th of 1938, was an Ideological propaganda unit that followed the establishment of the People Front by Comintern in 1935 and the China-Japan war that broke out in 1937. It had a huge organization, connecting regions, work places, communities, fraternities and even homes, and initiated various kinds of anti-Communism propagation activities through movies, plays, posters, writing and exhibitions. It tried to develop anti-Communist notions that would appeal to the general population, and to put an image of an ultimate evil upon Communism in general. Its objective was to block the Communist factions’ activities, crush the soft communization strategy of the People Front, and surround the entire society with an anti-Communist net. But despite the sheer volume of propaganda it was spewing out, and the well-designed organizational structure of it, the Joseon Anti-Communism Association had its own difficulties continuing its efforts. The reality of a colonized society, whose assets and properties were being mobilized in the Japanese war efforts, was dire to say the least. And it was not going to be changed or seem differently by mere propaganda. Poor peasants demanded economic merits and not philosophical enlightenment. Endless mobilization was considered only as a tiresome obligation that was disrupting one’s living. In the end, it failed. Then again, the actions of this association remained as an experience and a memory in the minds of the Korean people. Propaganda and propagation of the Joseon Anti-Communism Association continued to exist even in another period of ‘war,’ which followed the liberation, and became the origin of a social mechanism for ideological mobilization which would not hesitate to demand silence to voices of concern over inner conflicts and problems of the society.
