Cultural identity is an important psychological resource that supports young people’s sense of belonging, selfawareness, and psychological well-being. Children’s literature offers opportunities to strengthen these qualities by introducing readers to culturally meaningful narratives and positive role models. This study investigates the educational and psychological potential of the Who Is He/She? series published by Mazmundama Publishing House. The main goal of the study is to specify how biographical stories stimulate spiritual cultural identity, psychological well-being and vocabulary development using phraseological expressions. Using content and contextual analyses of selected books from the series, a qualitative research method was used with an emphasis on narrative structure, linguistic features and value aspects. The results incite readers to absorb values such as perseverance, responsibility, courage and respect for the national heritage as well as encourage emotional and cultural awareness. Rich literary language and phraseological units further support vocabulary development and meaningful learning. The study contributes to educational and social psychology by demonstrating that culturally grounded children’s literature can promote identity formation and psychological well-being. The findings may be applied in schools, libraries, and reading programs to support cultural education, language development, and the personal growth of young readers.
