Capital Moves to Seoul: The Joseon Dynasty Rises

Yi Seong-gye, the founder of Korea's Joseon Dynasty, relocated the capital from Kaesong to Hanyang on November 29, 1394, establishing a new political center that would anchor the dynasty for the next five hundred years. The move was strategic: Kaesong had been the seat of the preceding Goryeo Dynasty, and its corridors of power were saturated with political networks loyal to the old regime. Yi needed a location where his authority could grow without constant interference from entrenched aristocratic families. Hanyang offered natural advantages that complemented the political calculation. Nestled in the Han River valley and ringed by mountains on three sides, the site provided both military defensibility and access to waterborne trade routes connecting the interior to the western coast. Confucian advisors selected the specific location based on geomantic principles drawn from feng shui traditions, identifying the convergence of mountain ridges and river currents as auspicious for a seat of royal power. Construction of the primary palace complex, Gyeongbokgung, began almost immediately and continued for years. City walls stretching over 18 kilometers enclosed a capital designed to project the authority and cosmological legitimacy of the new ruling order. Government offices, markets, residential districts, and temples filled the valley floor according to a grid plan that reflected Confucian social hierarchies. Hanyang grew into one of East Asia's major urban centers over the following centuries. Today it is Seoul, home to roughly ten million people and the political, economic, and cultural heart of South Korea.
