Slavic mythology is a rich and complex collection of myths, beliefs, and supernatural beings that have shaped the cultural and spiritual identity of Slavic peoples for centuries. Although it is less well-known in the global context compared to Greek, Roman, or Norse mythology, it still holds an important place in literature, particularly in works intended for children. This paper examines how elements of Slavic mythology interfere with contemporary children's literature, contributing to the development of narrative structures, character portrayal, and the transmission of moral and ethical values. Special emphasis is placed on the analysis of works by Croatian authors such as Ivana Brlić-Mažuranić, Vladimir Nazor, Nada Iveljić, and Jasna Horvat, whose literary achievements are imbued with mythological motifs, archetypal characters, and symbolism drawn from Slavic traditions. By analyzing works such as Priče iz davnine (Tales from Long Ago), Veli Jože, Šestinski kišobran, and Krijesnici, this study explores how authors have adapted mythological elements for children's literature and integrated them into their narratives. The study concludes that Slavic mythology is not merely a historical relic but a vital part of contemporary literature that allows children to understand their cultural heritage, stimulates imagination and creative thinking, and conveys universal moral messages. By incorporating mythological elements into children's literature, authors not only enrich their stories with fantastic motifs but also enable a deeper connection between children and their cultural roots.
