This paper investigates the aspects of carnivalization in the dramas of Mate Matišić, Angels of Babylon, Cinco and Marinko, Sons die first and The Legend of St. Muhlo. In the first part of the paper, we will talk about carnivalization in general, about Bakhtin's understanding of carnival and the characteristics of carnivalization, such as ambivalent carnival laughter, grotesque realism, the material-physical principle, role reversal, feast images, the motif of death, etc. Then, the aspects of carnivalization will be searched for and analyzed in the selected works Matišić. In Matišić's plays, carnivalization manifests itself mainly through characters who deviate from social norms, situations that abound in dark humor and absurdity, and through the ironic portrayal of reality that is often distorted, grotesque and paradoxical. These elements allow the author to speak in a specific way about topics such as death, corruption, religion, war and transition traumas, emphasizing human nature and social anomalies. The carnival atmosphere in his works often leads the characters to situations where the boundaries between real and fantastic, serious and trivial are lost, which achieves the effect of destabilization and challenges the reader or viewer to question their own beliefs and values.
