孙吴立国具有肇始六朝的历史内涵。孙吴的皇权建构在内部受制于江东化进程，在外部受制于与魏、蜀的关系，经过了孙权称吴王与称皇帝两个阶段。汉祚终结时，江东内部并不支持孙权称尊号，孙权通过寻求曹魏的策命来建构王权。黄武四年（225）以后，孙权与江东大族的关系进入到顺畅期，同时外部压力减轻，故而孙权得以在黄龙元年（229）称帝并迁都建业。称帝后的孙权以压制官僚层来伸张皇权，留太子孙登守武昌，即针对陆逊等实权派官僚，然而皇权的分割导致太子成为皇帝之外的另一政治权威，动摇了皇权自我延续的根基。

The founding of the Kingdom Wu had historical significance to the founding of the Six Dynasties. The imperial power construction of the Kingdom Wu, interiorly restrained by the development of the region of Jiangdong (East of Yangtze River) and exteriorly influenced by the relationship between the Kingdoms of Wei and Shu, experienced two stages:SUN Quan's crowning himself as King Wu and then as the Emperor. At the end of the Han Dynasty, SUN Quan sought to construct imperial power through the royal order of the State of Wei reigned by CAO Family when he was not supported to claim King in the region of Jiangdong. After the fourth year of Huangwu (225 C. E.), the relationship between SUN Quan and major clans in Jiangdong became smooth, together with loosened exterior stress, and hence SUN was able to claim Emperor and establish the capital in Jianye (today's Nanjing) in the first year of Huanglong. After his claim of Emperor, SUN expanded his imperial power by suppressing the bureaucracy. His assignment of Prince SUN Deng to guard Wuchang City was actually an action of suppressing[JP2]bureaucratic officials such as LU Xun who had real power. However, the division of imperial power led to the result that Prince became another imperial authority besides the Emperor, which shook the foundation for the imperial power to continue.
