In 1392 the general Yi Song-gye overthrew the Goryeo dynasty and founded Joseon in its place, and with the new dynasty came a new state ideology chosen deliberately to mark a break with what had come before. Where the Goryeo court had favoured Buddhism as its own guiding faith, Joseon's founders installed Neo-Confucianism as the framework the state itself would run on, a deliberate rejection of the religious order the kingdom it replaced had kept for centuries.
That installation was not symbolic or ceremonial only. Neo-Confucianism governed Joseon's civil service examinations, shaping who could rise into government office; it defined the identity of the scholar official class that staffed the state from the capital down to the provinces; and it set the terms of the kingdom's ritual life, from court ceremony down to ordinary family practice, for five unbroken centuries of continuous rule.
What Joseon's founding changed for Confucianism's spread was durability on a scale few adoptions of the tradition outside China itself can match. A single dynastic founding in 1392 carried Neo-Confucianism into government, examination and ritual so completely that it held that position for five hundred years, one of Confucianism's most lasting establishments anywhere as the organising ideology of a state beyond its own homeland.
