Jecheon
Jecheon occupied an inland basin among Korea's central mountains, where routes linked Chungcheong with the neighbouring provinces. It received the name Jecheon in 1413 under the Joseon dynasty. Its local Confucian school had already been founded in 1389, and moved to Gyodong in 1590. There, instruction and ritual shared the same compound: the lecture hall served students, while the shrine honoured Confucius and other sages.
The mountain country also sheltered people at odds with the state. During the Catholic persecution of 1801, Hwang Sa-yeong hid in a dugout at Baeron, within the Jecheon district. He wrote a detailed letter on white silk describing the persecution and seeking help from the bishop in Beijing. The letter failed to reach its destination, and Hwang was arrested and executed. Between the recognised institutions of county government and Confucian learning, and the clandestine Catholic community at Baeron, Jecheon's religious history reflected the conflicting loyalties and dangers of late Joseon society.
