The problem of understanding of the political status of Bohai state.

The problem of understanding of the political status of Bohai state. Bohai (698 - 926) was a medieval state in East Asia. Tang Empire in 713 recognized Bohai as dukedom and considered this state as kingdom from the 760s. However, status of Bohai was unclear. Although Bohai was a formal vassal of the Tang Empire, it followed its own independent path, not only in its internal policies, but also in its foreign relations. Furthermore, it regarded itself as an empire. The aim of this article is to consider and analyze specifics, changes of political status of the Bohai state and its influence to international relation and position of Bohai population in East Asia at medieval period.
