The goal of master's thesis entitled Affirmation of the female voice: Zagorka and the trivial genre is to show the cry of female voices in her works, a cry that was inspired by Zagorka's own events. The synthesis of historical and romance novels created works that were accepted by the audience, and Marija Jurić Zagorka was recognized as an outstanding phenomenon in the field of trivial literature. The heroines of her novels are not just beautiful princesses waiting for their prince, they are heroines who fight for their principles and go through rebellions and revolts. So far, Zagorka's works have been studied in the context of trivial literature, and this paper will also consider the affirmation of the female voice through her works. The paper will analyze the cry of female voices in nine of Zagorka's novels, and the emphasis will be placed on Zagorka's pioneering work - The ranee from Petrinjska street. Interweaving crime fiction with historical and social context, Zagorka, in addition to affirming the female voice, effectively raised the position of the genre in Croatian literature. At a time when women's roles were strictly defined, her characters broke stereotypes. There is no doubt that Marija Jurić Zagorka is a woman ahead of her time. Although times have changed significantly, it would never have happened if it weren't for people like her who were ahead of their time.
