The purpose of the article is to verify the hypothesis that the idea of Polish heroism constitutes an effectively duplicating and spreading meme, and stories of the past constructed in the framework of Polish politics of memory will be effective precisely when they refer to memes duplicated most often in the community. The article proves therefore that the Polish state politics of memory should be shaped on the basis of memes that replicate the most in Polish society, because only then does it have a chance to achieve its goals. What is more, this principle can also be applied to other countries that pursue a politics of memory. It was possible to obtain answers to the research questions raised in the text (in order to verify the hypotheses) due to the use of mutually complementary research methods: analysis of narrative structures and content analysis. The article presents the results of the author’s own research with comments and conclusions.
