The author of the article examines the essence of the “founding myth” concept and analyses its role in legitimizing the power in the III RP. She reconstructs the theory basing upon Polish and international scientific output. The author asks whether referring to certain „founding myths” of post-Solidarity political groups is more then a manipulation, which may pass like an ordinary political trend or if it is the definition of a constant domination in shaping the ideological and political system of contemporary Poland. The author also analyses theoretical connection between the “political myth” and “founding myth” and their effects on social consciousness. She recalls the best known “political myths” from Polish history and determines whether the Polish people are easily affected by political mythologization among constantly arising new “founding myths” as it happened in the past. There is no doubt that referring to the “founding myths” in current politics deepens the socio-political divisions in Poland.
