The content of this thesis includes biographical notes on the Croatian writer Anđelka Martić. In addition to her biography, the stages of her literary work are also described and the writer's selected works are analyzed. Anđelka Martić started her literary work very early, so the opus of her works, as well as the phases in which she wrote, are various. Anđelka Martić appears for the first time in children's literature with the work called "Little Horseman". Prior to that, she wrote for various magazines, mostly war reports during World War II. Her most significant work is the children's novel "Pirgo", for which she received numerous awards. Both mentioned works belong to her first, that is war phase of creation. Since the writer herself took part in the war, she had the need to present war motives in her works. The war phase is followed by a phase in which the writer wrote about the events of her childhood. Characteristic features of both phases are realistic descriptions of events, because her works are mostly based on real events she experienced or heard, and the people she met. Thus, we can see autobiographical elements in her work, which give us an insight into the writer's life. After this phases, which included mostly war and childhood motives, Anđelka started writing fantasy literature. Her last two collections of stories are fairy tales with fantastic characters and events. With this, the writer moved away from realistic motives and indulged in her own imagination. Anđelka Martić subordinated her literary work to the influence of the environment and the people she was surrounded by. She managed best in factual presentation, with which she began her writing days, and it followed her until the last phase of her work. The element that connects all these phases are the lyrical descriptions of the forest, which she loved and appreciated since childhood, and are found in almost all of her works.
