Abstract
The civil examination system in the Confucian state of Yi Dynasty Korea was an important channel of recruitment for government officials and the graduates of the civil examinations carried enormous power and prestige. The determination as to who participated in these examinations will shed more light on the nature of Yi society. Contrary to the prevailing belief that the civil examinations were open only to men of yangban birth and closed to the commoners, there is strong evidence suggesting commoners' participations in the examinations. Legally, there was no statutory restriction against commoners. The state educational system that trained the future examination candidates not only did not discriminate against commoners but even encouraged qualified commoners to enroll in schools. Moreover, certain social groups whose social status was clearly lower than that of commoners were also allowed in the examinations. There were also individual cases in which men of non-yangban origin rose through the civil examinations to become government officials, some holding high ranking posts. In view of such evidence, the notion that the yangban status was wholly hereditary is no longer tenable. Instead, what distinguished yangban from commoners was one's determination and commitment to pursue Confucian scholarship by enrolling in a Confucian school, for student status exempted him from burdensome military duty.
