The Polish Law and Justice party has initiated domestic policies and regulations that challenge women’s rights. Poland is a member of the European Union where the gender inequality issues have never had such a high priority before and the union is currently operating under the Gender Mainstreaming strategy alongside with additional approaches. The two folded aim of this thesis is to create an understanding on how the Polish politicalauthorities can present backsliding tendencies of women’s rights by studying how thedomestic political institutions frame gender equality policies and Gender Mainstreaming followed by how the Polish political agents can legitimize the framings and implementations to the Polish society through the public discourse. A qualitative discourse analysis will be applied on materials from the EU, Polish politicalprograms and secondary sources such as news articles. The empirical findings suggest that the backsliding is part of a non-linear process where the Polish framing and implementation of policies on gender equality both converge and diverge from the EU. In the latest years, an incremental process of backsliding tendencies has appeared. As for the political discourse, the gender equality policies often end up in the background, overruled by pro-family policies. Also, the inadequate implementations and domestic framings is legitimized by the referencesto the foundational ideas of Polish society, where the EU challenges the traditional familywith “harmful gender ideologies”.
