How does leyasu justify the society hierarchy in Tokugawa japan?

Tokugawa Ieyasu justified the social hierarchy in Tokugawa Japan by emphasizing a Confucian worldview that prioritized order and stability in society. He established a strict class system with samurai at the top, followed by farmers, artisans, and merchants, arguing that each class had a specific role that contributed to the greater good of the state. This hierarchy was seen as essential for maintaining peace and preventing chaos, with loyalty and duty emphasized as core values. By promoting these ideals, Ieyasu aimed to solidify his power and ensure social harmony during a period of relative stability.
