This paper examines the lifespan of the kings of Goguryeo and presents the following findings: first, the kings of Goguryeo tended to be mature when crowned and have lifespans average for them, which ensured the succession of an heir capable of managing state affairs. Royal authority could thus be maintained steadily. Second, the kings reigning during state reformations ascended the throne after reaching adulthood and died late in life, when their successors were old enough to take over the state. Successful social reform was consequently possible even amidst undesirable situations. Third, the kings who reigned in the time of decline present opposite traits from the kings who undertook social reforms. The age of the king also influenced the political situation after mid-6th century. Young kings found it difficult to efficiently exercise power. In short, the lifespan and age of the kings played a crucial role in the history of Goguryeo, because the king was the center of the state during the pre-modern age.
