The intention of this final paper is to study and present the work of one of the key Croatian writers from the time of Romanticism, Dragojla Jarnević. The paper focuses on the way of narration in her "Diary" because the overall work is much more comprehensive. In the introductory part, the analysis is connected with literary theoretical nomenclature, followed by a brief description of Dragojla Jarnević's life. The next chapter places "The Diary" in the context of the period in which it was created and deals with the reactions to the printed editions of both the fragments of this manuscript and its integral edition from 2000, edited by Irena Lukšić. The central chapter deals with the autodiegetic narration and describes the key aspects, namely intimacy and authenticity, subjectivity, character development and reflexivity. The autodiegetic narration in Dragojla Jarnević's "Diary" enables a deeply personalized presentation of her life and an understanding of the wider social and historical context in which she lived. Through this narrative technique, she manages to create a work that is both intimate and universal, personal and socially significant. The paper ends with a final reflection on the work and character of Dragojla Jarnević and observations about the style of writing in the first-person characteristic for a diary, which is also connected with the poetics of romanticism.
