The Protestant missionaries contributed much to the development of Western education in Joseon Korea. The Queen Consort, unlike her father-in-law, who had oppressed Christians, invited different missionaries to enter Joseon. She knew and valued their knowledge of Western history, science, and mathematics, and was aware of the advantage of having them within the nation. Unlike the Isolationists, she saw no threat to the Confucian morals of Korean society in the advent of Christianity. Religious tolerance was another one of her goals.
