Abstract: Unlike the historical process of gradual monarchical absolutism in mainland countries, medieval Japan was in a stage of unclear ownership of exchange items for a long time, which increased the degree of master-servant dependence within and between social classes, leading to the long-term dominance of the expansionist compound regime in the entire society. Among them, the social stratification caused by the expansion of the composite regime dominated by the court led to the gradual abandonment of the exchange system dominated by the court and the active creation of its own dominant exchange circle by the samurai class with highly consistent “aspirations and identity”. Its external political manifestation is that the expansion of the composite regime dominated by the samurai initially became the social dominant form after the land and the conquest of Mutsu, which blocked the exchange channels between the middle and lower class samurai and the court, causing the court to lose the support of the emerging samurai class, and gradually fell behind in the confrontation with the shogunate. The Chengjiu Rebellion is a strong proof.
