This article examines the trends in the development of Kazakh children's literature in the 1950s and 1960s, focusing on its thematic and ideological orientation. It also delves into the creative world of poet Adyrbek Sopybekov, whose significant contributions to the field are explored. The author analyzes fantastic poems and other selected works by A. Sopybekov, considered the best examples of children's poetry, and paying close attention on their thematic, ideological features, and artistic aspects. Children's poetry during the years of national independence remains a relatively understudied topic. Examining the creative laboratory of poets who have worked significantly in this direction, and thereby studying the direction and nature of modern children's poetry, drawing conclusions about thematic and ideological features, artistic aspects, is one of the urgent tasks facing the science of national literary studies. While valuable insights into Adyrbek Sopybekov's children's works have appeared in the press, a dedicated, comprehensive analysis of his creative portrait within the framework of Kazakh literary studies is still lacking. This article aims to address this gap by offering a broader differentiation of the poet's work, thereby assessing his characteristic style, his methods of conveying artistic ideas to children, and the educational value inherent in his writing. Additionally, it seeks to evaluate A. Sopybekov's contributions to Kazakh children's literature of the 1950s and 1960s and to gain a deeper understanding of his poetic skill.
