The source of discrimination seems to be also present throughout Korean history.
This has been investigated in my research paper “Korean Shamanism: Religious Syncretism in Early Korean Dynasties.” The Joseon dynasty, Shamans, symbolizing a non-scholarly and gender-challenging perspective, were relegated to the lowest class alongside Buddhist monks, disrupting the Confucian patriarchal structure.
Female shamans, particularly, were vilified as disruptive to family hierarchies, deemed "evil" and corrupt. King Sejong's reign formalized the denouncement of shamanism by the Office of Censor-General, labeling it as a threat to the righteous management of family and societal affairs.
