The territory and governments of the Zhou dynasty and the Qin dynasty were unified after the conquests of Qin Shi Huang, and the concept of "tianxia" was adapted to act as an actual geographic entity. Qin Shi Huang's goal to "unify all under Heaven" was, in fact, representative of his desire to control and expand Chinese territory. At the founding of the Han dynasty, the equivalence of "tianxia" with the Chinese nation evolved due to the feudal practice of conferring land and autonomy upon the aristocracy to avoid having to expend military expense in their subjugation. Although many areas enjoyed great autonomy, the practice established and spread Chinese language and culture throughout an even wider territory.
