Previous research has established a link between the level of transposition of EU legislation and the national government’s characteristics and preferences. In the area of gender equality this has been labelled as the national gender regime of a country. Studies from Ostner and Lewis and Clavero and Galligan have shown that this gender regime can constrain a country in transposing the EU’s gender legislation. This thesis continues this path of research by examining the levels of transposition and gender regimes in Croatia and Turkey. Both of these countries are compared to Slovenia, which had been identified in earlier research as easily complying with EU legislation. It finds that challenges to transposition continue to exist in Croatia and Turkey. However, all of the three countries, including Slovenia, show a different gender regime and a different transposition performance. This study concludes that the EU is able to influence these countries on different levels because of the countries’ gender regimes.
