In Korea, centralized government has existed for a long time. The Goryeo Dynasty, which emerged in the tenth century, strengthened the power of the centralized authoritarian government within an intimate relationship with the local powers called hojok of the time. This period may be compared to the feudal ages of the West in that the centralized power coexisted with the local hojok powers. The Chosun Dynasty, which emerged in the late fourteenth century, established a powerful and centralized political, economic, and administrative system under the idea of Confucian rule. In this context, it may be said that Korea’s centralized system has a tradition dating back more than 600 years.
