The era of the Soviet Union proved that real national literature cannot be created under colonialism. The "socialist realism" method created by the authorities had a reverse impact on the nature of the artistic image. The characters in the work are politicized. Special attention was paid to the class division (rich and poor), and the images were depicted one-sidedly. The collapse of the USSR allowed the development of a new type of literature in the post-Soviet countries. In the research paper, we made comparisons, and the damage caused by the method of "socialist realism" to fiction is mentioned. However, these years were also successful. Kazakh literature has developed in terms of genres. The genre of the novel has been mastered. Talented writers have mastered describing the reality of life with clues. Literary tradition and skill practices were used in the literature of the period of Independence. The fate and history of the nation were shown in innovative novels. Modern realities and changed human psychology were depicted together with the world space. A stream of postmodern, realistic novels came to literature. The release of the novel from political restrictions allowed genre change (historical, biographical, satirical, fantasy, etc.). The storytelling style has been renewed. There was new artistic and stylistic research in creating a hero’s personality.
