In this thesis the relationship of Croatian novelist and one of the main representatives of realism in the Croatian literature Ksaver Šandor Gjalski and the Croatian Catholic literary criticism towards the Rightist political movement and towards the writers familiar with Rightism (Ante Kovačić, Eugen Kumičić and Silvije Strahimir Kranjčević) will be analysed. Gjalski's critique of Rightist movement in his novel U noći will be taken into the consideration and after analysing the original Rightist political-literary texts (Ante Starčević's political texts, Ante Kovačić's novel Među žabari etc.) the final remark of the literature of authors familiar with Rightism and of the Rightist movement will be given. Indeed, the texts of Croatian Catholic literary critics, which seem not to have had an equal statement towards the Rightism (if we compare, for example, Kerubin Šegvić's and Jovan Hranilović's texts along with, indeed, Jakša Čedomil, the founder of the modern Croatian literary criticism) will be taken into the consideration. In the Introduction the relevant bio-bibliographical data on Ksaver Šandor Gjalski, mentioned writers familiar with Rightism and Croatian Catholic literary critics will be given. Then in the central part the context of the Rightist political movement's and the literature work of authors familiar with Rightism will be taken into the consideration. Afterwards Gjalski's and the Croatian Catholic literary criticism's relationship towards this political movement and literature will be analysed. In the conclusion are, in short, given the results of the inquiry and the thesis as the whole is finished.
