The politics of the Joseon dynasty, which ruled Korea from 1392 to 1897, were governed by the reigning ideology of Korean Confucianism, a form of Neo-Confucianism. Political struggles were common between different factions of the scholar-officials. Purges frequently resulted in leading political figures being sent into exile or condemned to death.
The political system of this period was dominated by a Confucianist bureaucracy. The government officials were ranked in 18 levels, ranging from senior first rank (jeong-il-pum, Korean: 정1품; Hanja: 正一品) down to junior ninth rank (jong-gu-pum, Korean: 종9품; Hanja: 從九品) based on seniority and promotion, which was achieved through the royal decree based on examinations and recommendations.
The power of the bureaucrats often eclipsed that of the central authorities, including the monarch. For much of the dynasty, a complex system of checks and balances prevented any one section of the government from gaining overwhelming power until the 19th century when political power became concentrated in a certain family or individual.
