This article presents a literary-theoretical analysis of the assimilation of Gothic literary traditions in the novels of the American writer Stephen King and the national transformation of the genre. The aim of the research is to illuminate the literary-aesthetic foundations of Kingʻs works within the context of the traditions of Horace Walpole, Ann Radcliffe, Mary Shelley, Bram Stoker, Edgar Allan Poe and Howard Phillips Lovecraft, and to identify how the system of Gothic motifs is recreated in Kingʻs novels. The formulation of the problem is grounded in the fact that the integral system of Gothic traditions in Kingʻs novels has not been sufficiently illuminated in Uzbek literary studies. The research is conducted on the basis of literary-theoretical, linguopoetic, and structural-semantic approaches. Stephen Kingʻs novels “The Shining”, “Salemʼs Lot”, “It” and “Pet Sematary” have been selected as research material; Kingʻs theoretical work “Danse Macabre” has been analysed as a primary source. The research findings demonstrate that King has democratized the genre by transferring the aristocratic European forms of the Gothic tradition into the American working-class environment, and has reinterpreted classical Gothic motifs the vampire, the ghost, the cursed building, demonic forces as artistic metaphors of contemporary social problems.
